The United States is leaning on a broad network of safeguards and oversight bodies to monitor billions of dollars in aid flowing to Ukraine, as Kyiv continues to confront long-running corruption concerns during its war effort, a regional security expert said Sunday.
That scrutiny comes at a politically sensitive moment for President Volodymyr Zelenskyy, whose inner circle has faced mounting pressure from expanding investigations. Since 2025, multiple senior officials and aides have resigned, been removed from their posts or come under investigative review.
On Aug. 19, Zelenskyy removed Iryna Mudra, a deputy head of the presidential office, as anti-corruption authorities pursued a money-laundering probe tied to another deputy head of the office.
Mudra has not been identified by investigators as a suspect, The Associated Press reported.

“Of course, in all of the former Soviet Union countries, there is significant corruption,” former Deputy Assistant Secretary of State Carrie Filipetti, now executive director of the Vandenberg Coalition, told News Outlet.
“A lot more work needs to be done. But we know, at least on the U.S. side, as we’re providing support for their military, we have a lot of mechanisms,” she said, pointing to the dozens of agencies involved in tracking and overseeing American assistance to Ukraine.
According to congressional reports, Washington committed $67.8 billion in defense articles and services to Ukraine between February 2022 and March 2026 through the Presidential Drawdown Authority, the Ukraine Security Assistance Initiative and Foreign Military Financing.
That support is part of a broader U.S. response to the war.
About $195 billion has been appropriated for Operation Atlantic Resolve, including funds to replenish U.S. weapons stocks, support U.S. military operations in Europe and provide economic, development and humanitarian assistance, according to the Council on Foreign Relations.

“Over 24 federal agencies are involved in oversight,” Filipetti said. “To make certain that there are no consequences to the U.S. taxpayer, to our equipment in terms of the corruption issue, U.S. contributions are very much protected.”
In recent months, however, senior Ukrainian officials have resigned, been dismissed or faced scrutiny by the country’s independent anti-corruption bodies, including NABU.
Those developments include Andriy Yermak’s Nov. 28, 2025, resignation after investigators searched his premises and Mudra’s Aug. 19 dismissal during a money-laundering probe.
Former Deputy Prime Minister Olha Stefanishyna was dismissed by Zelenskyy as Ukraine’s ambassador to the U.S. on Aug. 3, two days before a suspicion notice was served against her, according to the Kyiv Post.
He also fired Defense Minister Mykhailo Fedorov on July 15 in a broader reshuffle over internal wartime disagreements which sparked protests across the nation.

In interviews after he left government, Fedorov also complained about what he described as ingrained corruption and patronage networks, Reuters reported.
“We’ve seen that Zelenskyy is taking really seriously the criticisms of corruption, and every time there is an allegation, he moves very swiftly to remove those individuals from the government,” Filipetti said.
“And the fact that there are these independent bodies is, I think, really important. They’re listening to them. They’re making sure that they’re trying to root it out as much as humanly possible.”

Zelenskyy has pushed back on suggestions that the investigations implicate him personally.
“The heads of anti-corruption agencies have zero questions for me,” Zelenskyy said in remarks published Aug. 23 regarding the investigations. “They understand perfectly well that I am not involved in anything like that.”
A February 2024 USAID inspector general review also found that the agency did not independently verify some Ukrainian health workers’ salary claims before reimbursement, though Filipetti said U.S. economic aid is now reimbursed only after verification.
“A lot of what the United States has been providing, we’re making sure that everything is through a reimbursement mechanism,” Filipetti said.

She said U.S. aid has not been tied to the money-laundering allegations and remains protected as Ukraine works to combat corruption.
The scrutiny also comes as Kyiv faces shortages of Patriot interceptors amid intensified Russian strikes and a need for air defense interceptors.
Zelenskyy said he wants to secure 300 additional interceptors for the coming winter, while Ukraine’s air force has requested 360.
“One of the most urgent needs that the Ukrainians have right now is interceptor missiles,” Filipetti said. “This is why this idea of sending Patriot capabilities and allowing them to produce them on the ground in Ukraine has become so important to Zelenskyy.”

President Donald Trump has expressed reluctance to further deplete U.S. missile inventories, saying the United States also needs the weapons, while pressing European allies to shoulder more of Ukraine’s defense burden.
“We want missiles too,” Trump said Aug. 6 when asked about Zelenskyy’s requests for long-range missiles and Patriot systems. “Biden gave him so much, Biden gave $300 billion worth of ammunition.”
Filipetti also said Ukraine’s anti-corruption efforts remain an important consideration for its NATO aspirations.
“I think every country has been really adamant that the Ukrainians move forward in their anti-corruption mechanisms,” Filipetti said.
“Obviously, if Ukraine ever wants to be a formal member of NATO, that’s something that they will need to prove and demonstrate.”
