President Vladimir V. Putin of Russia agreed on Tuesday during a phone call with President Trump to halt strikes on Ukrainian energy infrastructure, the Kremlin said in a statement, but restated his concerns about a broader 30-day cease-fire that the United States and Ukraine had agreed upon and proposed to Russia.

Ukrainian officials have accused Mr. Putin of playing for time in order to maintain leverage in negotiations, and allow Russia time to continue bombarding Ukrainian cities and towns.

During the call, Mr. Putin said his “key condition” to end the conflict and prevent it from escalating was a “complete cessation” of foreign military and intelligence assistance to Kyiv, the Kremlin said.

In a call with President Trump, President Vladimir V. Putin agreed to pause strikes on Ukrainian energy infrastructure for 30 days. That falls short of the unconditional cease-fire Ukraine had already agreed to.

Ms. Okose fears they are drug-resistant. She collected sputum samples from them and their three siblings the day before the inauguration. The testing is frozen, and all five children continue to sleep under one blanket at night.

But because all the TB and H.I.V. cases have gone to the separate clinics for years, clinicians in the main facilities don’t know about drug protocols, side effects or signs of treatment failure.“You will have health care workers who have never seen a TB case; there will be quality-of-care issues,” said Dr. Timothy Malika, who oversees the TB program of Kisumu County, which has one of the highest rates of TB infection in Kenya.

The aid cuts have also crippled a network of clinics set up all over Africa two decades ago by President George W. Bush’s Emergency Plan for AIDS Relief. Those clinics bypassed the frail, bureaucratic and graft-riddled health systems in countries battling TB and H.IV. and put patients on lifesaving medication quickly. Twenty years later, they were still partly or totally separate, in most places, and had U.S.-paid staff.Now African health officials are scrambling to absorb those patients into the regular medical system — as many as 40 percent more people to care for, in facilities that were already overstretched. Kenya’s national government has said it is working on a plan but offered no details for how it will bridge the yawning funding gap.

The TB Champions, who drop in to check in on anyone they hear about with a persistent cough, were intended as a low-budget, high-impact strategy to change that. Since the aid freeze, they have taken on outsize importance. In the scruffy western Kenyan town of Busia, a Champion named Agnes Okose is using the money she earns from her snack stall to fund trips to outlying villages. Since late January, she has been delivering diagnoses and collecting sputum samples in plastic sample jars she buys herself, toting them in a small lunch cooler to a laboratory in town.

While he is on the drugs, Mr. Odima is supposed to have monthly testing of his blood, liver and kidneys to make sure his body is tolerating them. That costs about $80, previously covered by the U.S. grant, and he has not had a test since the funding freeze. Mr. Odima’s wife and five children are supposed to be rechecked for the disease this month; it will take all his savings to pay for X-rays.

Good news came back: Mr. Modore did not have drug resistance and could take the standard medications.But there was no one to prescribe them. The staff members at the clinic were paid by the United States, and they were now fired. Ms. Kikuyu was at her wit’s end, knowing Mr. Modore was desperately ill.

But across Kenya, the community advocates have kept working, unpaid, covering the costs of trying to reach patients and delivering diagnoses out of their own pockets.

Despite being fully treatable, tuberculosis claimed 1.25 million lives in 2023, the last year for which data is available. If TB begins to spread unchecked, people throughout the world could become at risk.

Family members of infected people are not being put on preventive therapy. Infected adults are sharing rooms in crowded Nairobi tenements, and infected children are sleeping four to a bed with their siblings. Parents who took their sick children to get tested the day before Mr. Trump was inaugurated are still waiting to hear if their children have tuberculosis. And people who have the near-totally drug-resistant form of tuberculosis are not being treated.Image

The United States contributed about half of international donor funding to TB last year and here in Kenya paid for everything from nurses to lab equipment. Trump administration officials have said that other countries should contribute a greater share to global health programs. They say administration is evaluating foreign aid contracts to determine whether they are in the national interest of the United States.

Many, like Mr. Modore, have grown significantly sicker. As they go about their lives, waiting and hoping, they are spreading the disease, to others in their own families, communities and beyond.

Mr. Modore has tuberculosis. He is 40, a tall man whose weight has dropped to 110 pounds. He has a wracking cough and sometimes vomits blood. He fears the disease will kill him and has been desperate to be on medication to treat it.Mr. Modore is one of thousands of Kenyans, and hundreds of thousands of people worldwide, with TB who have lost access to treatments and testing in the weeks since the Trump administration slashed foreign aid and withdrew funding for health programs around the globe.

Prices at the gas pump in the Northeast could rise as much as 40 cents per gallon by mid-March because of the 10 percent tariff on energy imports from Canada that took effect today, according to Patrick De Haan, the head of petroleum analysis at GasBuddy.

Senator John Thune, Republican of South Dakota, says Trump’s tariffs “are oriented around specific objectives, in this case, to reduce the amount of fentanyl coming in this country, across our borders. And so these tariffs, I think, are hopefully temporary.”

U.S. imports from China, Mexico and Canada totaled over $1.3 trillion last year, or about two-fifths of all imports.The tariffs apply a 25 percent duty on goods from Mexico and Canada and an additional 10 percent on imports from China.Importers typically employ customs brokers to calculate and pay tariffs to the government agency that collects them, U.S. Customs and Border Protection.Adam Lewis, a co-founder and the president of Clearit, a customs broker, said that it would not be hard to tweak software to collect the new tariffs, but that a crucial part of the tariffs payment system might need significant adjustments. Importers must buy a “customs bond,” a type of insurance that guarantees the duties will be paid. Mr. Lewis said some customers might have to increase the size of their bonds to cover the extra tariff payments.“Many of their products were coming in duty-free, and all of a sudden there’s going to be a 25 percent increase,” he said. “It’s quite large.”In addition, policing importers for tariff evasion will now become a much bigger task for Customs and Border Protection and the Department of Justice. Some importers may try to avoid tariffs by understating the cost of goods in customs declarations or by falsely claiming they were imported from countries not subject to tariffs.“The greater the breadth and severity of these new tariffs, the greater the likelihood that at least some potential importers may want to misrepresent the value or the origin of their goods,” said Kirti Vaidya Reddy, a former federal prosecutor who is now a partner at the law firm Quarles.If the government finds that an importer has not paid duties, customs officials are likely to demand that the importer pay what is owed and a penalty that can double or even triple the amount due.In a statement, a customs agency spokeswoman said: “The dynamic nature of our mission, along with evolving threats and challenges, requires C.B.P. to remain flexible and adapt quickly while ensuring seamless operations and mission resilience. These tariffs will help maintain America’s global competitiveness and protect American industries from unfair trade practices.”Some evasion cases have become the subject of criminal prosecutions. Last year, a Miami importer pleaded guilty to participating in an import scheme involving Chinese truck tires that the Justice Department said had cost the United States more than $1.9 million in forgone tariff revenue.But stepping up enforcement efforts is likely to require that the Justice Department devote significantly more staff to pursuing tariff evasion cases, which, lawyers said, can take time to build.“The Department of Justice has the personnel and infrastructure to do it, but these cases are complex, transnational and document-heavy,” said Artie McConnell, a former federal prosecutor who is a partner at the law firm BakerHostetler. “You can’t rush it, and prosecutions likely won’t come quickly.”

José de Jesús Rodríguez, president of the chamber of commerce of Mexico City, predicted economic turmoil for Mexico, including a possible recession and unemployment of as much as 15 percent, given the deep integration of supply chains between Mexico and the United States.

Mr. Trudeau labeled a trade war between the North American neighbors “very dumb” and portrayed Mr. Trump’s motives in attacking Canada, one of the United States’ closest allies, as furthering the territorial aggression that the American president has repeatedly expressed toward its northern neighbor.

“A fight with Canada will have no winners,” Mr. Trudeau said, just days before he is set to step down as prime minister.

Canada and China quickly announced retaliatory tariffs after the U.S. levies — an additional 10 percent on imports from China and 25 percent on almost all imports from Canada and Mexico — went into effect just after midnight on Monday. Mexico’s president, Claudia Sheinbaum, said her country could impose its own countermeasures by Sunday. The moves raised the stakes, and potentially the costs, of a brewing trade war that was already driving down stock prices and worrying global markets.

Economists have been bracing for tariffs ever since President Trump won the election last year. But the measures he took on Tuesday against the United States’ closest trading partners far exceeded what they expected, raising the risks of a much more significant blow to the economy.

Prime Minister Justin Trudeau of Canada on Tuesday harshly condemned the tariffs that President Trump imposed on Canada, as well as Mexico and China, saying in a televised address that they would hurt people on both sides of the U.S.-Canadian border and that Canada would “relentlessly fight” to protect its economy.

Global markets fell after stiff U.S. tariffs went into effect at midnight, and China and Canada immediately imposed retaliatory measures. Mexico said it would announce its response on Sunday.

As for Mr. Trump, the Russian leader praised him, calling him someone who “does not simply say what he thinks, but he says what he wants.”

He added that he had spoken with Mr. Putin about the possibility of deploying European peacekeepers to Ukraine to monitor any cease-fire and that the Russian president would go along with it.

But he quickly added that he approved of Mr. Trump’s new effort because his election presented “a new context.”

Mr. Macron has organized two meetings of European leaders to formulate a plan for dealing with an America that appears to be shifting favor from its traditional allies to Russia.

Mr. Trump, who failed to broker an end to the war in 24 hours or before his inauguration, as he had promised to do on the campaign trail, said that talks he had started with Mr. Putin could end the war “within weeks, if we’re smart.” He added, “If we’re not smart, it will keep going and we will lose young, beautiful people.”

Mr. Trump repeated the false claim that the United States had spent $350 billion to aid Ukraine and “had nothing to show for it,” while Europe had spent only $100 billion. In fact, according to the Kiel Institute for the World Economy, Europe has allocated $138 billion to the war effort, compared with the $119 billion given by the United States.

Mr. Trump made no mention of guarantees or Ukrainian sovereignty, refused to call Mr. Putin a dictator and falsely stated that the United States had spent three times as much on the war as Europe had. Mr. Macron, careful not to provoke Mr. Trump, made clear that Russia was to blame for the war, not Ukraine, and corrected the president’s assertions about European aid.

“It must not mean a cease-fire without guarantees. This peace must allow for Ukrainian sovereignty.”

“I think a lot of progress has been made,” Mr. Trump said of his efforts to negotiate peace with President Vladimir V. Putin of Russia. “We’ve had some very good talks with Russia. We’ve had some very good talks with others, and we’re trying to get the war ended with Russia and Ukraine.”

While many world leaders made the trek to Kyiv to stand with Ukrainian leaders, Mr. Trump focused on sealing a deal to claim the country’s natural resources as recompense for military aid.

While Europe and most of the world sided with Ukraine, the Trump administration dissented along with Russia, North Korea and Belarus, putting the United States in a camp that it has rarely if ever been in over the history of the United Nations.

The session came as the United States and France split sharply at the United Nations over a resolution condemning Russia’s aggression.

Meeting on the third anniversary of Russia’s full-scale invasion of Ukraine, the two leaders seemed intent on avoiding an open rupture as they traded compliments during a convivial White House meeting. But they diverged significantly over the causes of the war, each side’s role in the conflict and its possible resolution.

“I would say that when they want a seat at the table, you could say the people have to — wouldn’t the people of Ukraine have to say, like, you know, it’s been a long time since we had an election?” Mr. Trump said. “That’s not a Russia thing. That’s something coming from me and coming from many other countries also.”

Mr. Zelensky, who was not invited to the meeting, sharply criticized it and said his country would “never” accept a peace deal if Ukraine did not have a seat at the negotiating table.

Ukraine has little chance of recapturing its lost territory, particularly if the United States slows or stops the flow of military aid.

In all, Russia now occupies around 20 percent of Ukraine, but so far it has failed in its key objectives of breaking Ukraine’s military and securing Kyiv.

The International Criminal Court has also accused Mr. Putin of war crimes in Ukraine and issued a warrant for his arrest, along with another senior Russian official.

Since then, Russian firepower has leveled whole cities and killed more than 12,000 Ukrainian civilians, according to the United Nations.

There is no doubt that Russia started the war by invading Ukraine. Russian troops stormed over the border almost exactly three years ago, with the explicit aim of toppling the pro-Western government of Mr. Zelensky in Kyiv, the capital.

“You should have never started it,” Mr. Trump said, referring to Ukraine’s leaders. “You could have made a deal.” He followed up on Wednesday in a post on social media, calling Ukraine’s president, Volodymyr Zelensky, a “dictator without elections" and saying he had “done a terrible job” in office.

which became clear as Mr. Trump again restricted the use of American foreign aid to any organization around the world that provides abortions, or abortion counseling, even if those activities are legal in the country being helped.

“They’re a global charity, that they take the taxpayer money and they spend it as a global charity irrespective of whether it is in the national interest or not.”

So when the president talks about cleaning it out, he talks about making it habitable.”

And it was wrapped in an explanation that there was no other way to start the process than by evicting everyone and bringing in the bulldozers.

The two million Palestinians there would be moved elsewhere — voluntarily or forcefully was never made clear.

Mr. Trump declared that their leaders were “radical left lunatics,” and the State Department ordered them to halt virtually all their projects, even if that meant cutting off programs that helped eradicate smallpox and prevented millions of H.I.V. cases.

When I return to the White House, I will do everything I can to challenge the Impoundment Control Act in court, and if necessary, get Congress to overturn it.”

Another part of the statute, as amended in 1987 by Congress, says the president is supposed to send lawmakers a detailed and specific notice about such a delay, including its rationale and when it will be over.

Impoundment would be another way of essentially doing the same thing — if it is lawful.

Legalizing permanent impoundment would transfer power from Congress to the presidency.

Congress essentially banned presidents from unilaterally and permanently impounding funds in a 1974 law.

On Monday, the White House, in a memo, ordered a temporary halt to “all federal financial assistance” like loans and grants on domestic soil as well.

That freeze has jeopardized a broad swath of congressionally authorized aid, like military assistance to Ukraine in its fight against Russia’s invasion, helping pay the salaries of a Kurdish-led militia guarding Islamic State detainees in northeast Syria and the distribution of anti-H.I.V. medication in Africa and developing countries.
