After the Trump administration upended the world’s largest foreign aid provider last year, terminating thousands of programs and firing nearly all of its staff, its plan for the agency was clear: Eliminate it entirely.

But because it is a congressionally created agency, President Donald Trump needed lawmakers’ permission to do so. So this year, Trump officials asked Congress for permission to shutter the U.S. Agency for International Development and dramatically reduce federal spending on food, medicine and lifesaving work around the world.

Congress said no. Lawmakers, who hold the government’s purse strings and have oversight of federal agencies, wanted USAID to remain, even in its diminished form. They detailed precisely how much the State Department should spend on foreign aid and for what, including $9.4 billion on global health to treat and prevent maladies like HIV, tuberculosis and malaria, and more than $5 billion on emergency humanitarian aid. They also insisted on regular, detailed reports about how the administration was spending the money.

Trump signed the bill, enshrining their orders into law.

Now, eight months into the fiscal year, Trump officials are failing to follow many of those orders, ProPublica has found. Officials have delayed spending on global health, have not issued funds for some projects and have labeled money destined for humanitarian aid as “unallocated” to control how it can be spent, according to a ProPublica review of government records and interviews with legal experts, current and former government employees, and members of Congress. And when lawmakers have asked about their actions, officials often have not responded.

The White House and Congress have been battling over federal spending since Day 1 of the Trump administration, setting up a constitutional crisis — a breakdown of the division of power among the three branches of the federal government, according to several legal scholars.

Nowhere has that crisis been more visible than with foreign aid. Last year, the administration took the unprecedented step of gutting USAID, terminating thousands of aid programs and letting funding expire, all without permission from Congress. Lawmakers did little to stop it.

Now, in defying Congress on foreign aid that Trump himself agreed to spend, the administration is quietly escalating the battle.

“It is a huge grab of power from the president, taking powers away from Congress,” said David Super, a professor of law and economics at Georgetown University and a leading scholar on administrative and constitutional law.

USAID was created by Congress decades ago as a means of promoting American diplomacy and soft power around the world. As ProPublica ly reported, when Trump officials dismantled the agency last year, stopping payments on thousands of lifesaving programs that provided food, medicine and other supplies to impoverished nations, many people died, including children.

Even with USAID in shambles, Congress has made clear that it expects the administration to continue providing foreign aid — in some cases, at nearly the level it did in years.

“It’s proof that there is still broad, bipartisan support for America showing up in the world, helping people and working with our allies and partners on shared challenges, not just because it’s the right thing to do, but because it directly benefits us,” said Sen. Brian Schatz, D-Hawaii, the ranking member of the Senate committee with oversight of foreign aid funds. Sen. Lindsey Graham, R-S.C., the committee’s chair, did not respond to multiple requests for comment.

But the administration has taken a variety of steps to thwart Congress’ directives. The Office of Management and Budget, run by Russell Vought, was instrumental in blocking the spending of aid money last year. This year, it has labeled both humanitarian aid and global health money as “unallocated,” meaning the OMB must approve how it is spent.

Legal scholars say such moves, and the delayed spending by the State Department, likely violate the law. Foreign aid is a prime example of why Congress made it illegal for administrations and agencies to slow-walk such funds, said Bobby Kogan, an OMB adviser under former President Joe Biden currently with the Center for American Progress. “If you spend no money for a year and all the clinics close, then those people die,” he said.

The State Department has made little effort to spend some foreign aid money that Congress earmarked for specific purposes, including family planning, neglected diseases and nutrition, according to government staff and budget documents.

And programs have been given fewer dollars, even when Congress has kept funding steady. That includes the President’s Emergency Plan for AIDS Relief, the hallmark HIV program credited with saving 26 million lives around the world.

Administration officials are also spending on foreign aid at a much slower rate than they had in recent years, according to an analysis of federal funding data shared with ProPublica by Aid on the Hill, an advocacy group created by former USAID employees, although the State Department disputes its conclusions. Another group published a similar analysis last week.

Where Trump officials have made plans to spend funds, it’s often spurred outrage. Under the new America First Global Health Strategy, Trump officials are signing bilateral deals with poor countries, asking for access to health data as a condition for receiving lifesaving medications the U.S. once donated.

Jeremy Lewin, a 29-year-old lawyer who came into government via Elon Musk’s Department of Government Efficiency with no prior humanitarian experience, is in charge of foreign aid. He has said that this new strategy will not only save countless lives, but also reform the aid sector and reduce dependence on U.S. funding.

Since last July, Lewin has been “performing the duties” of undersecretary for foreign assistance and humanitarian affairs, a position that must be approved by Congress, though the administration has yet to nominate him or anyone else to the job.

But he rarely, if ever, meets with career staff and doesn’t share information about his plans, even with the people who are expected to carry them out, according to six current and former career officials. Lewin insists that he approve even routine payments, creating a stranglehold on funding and information.

And all the while, Trump appointees have failed to answer basic questions from Congress about what they are doing. Letters from lawmakers have gone unanswered and required reports unfiled.

To understand the administration’s compliance with congressional mandates and federal law, ProPublica reviewed administration documents, including agreements, memos, and internal communications, and spoke with dozens of current and former government officials, congressional staff, and international experts in global health and humanitarian aid. Many people spoke on the condition of anonymity for fear of reprisal from the administration.

In response to a list of detailed questions about the concerns, a State Department spokesperson who declined to be named said they would continue to follow the president’s direction on foreign aid spending. “We are not withholding any funds appropriated to, or available to, State,” they said. “If additional funds are made available to State, we will work to obligate them consistent with legal requirements and Administration priorities.”

They said officials have regularly briefed Congress and that Lewin had recently spent four hours discussing foreign assistance. They also said they have “reduced by 80% the number of outstanding reports and letters” since Trump retook office.

“We are working with Congress to spend appropriated balances and find the right future-appropriated level for global health,” the spokesperson said.

In response to a series of detailed questions about this story, OMB spokesperson Rachel Cauley said, “This is pate
