The White House is withholding $400 million in military aid for Kiev approved by the US Congress, Senator Dick Durbin has said. The funding, allocated by lawmakers in January, will not be available until at least 2029, he said during a hearing on Wednesday.

The money is part of the Ukraine Security Assistance Initiative (USAI), a Pentagon-led program under which the Ukrainian military receives training, equipment, and advisory assistance from the US.

According to Durbin, the January package has yet to reach Kiev and has so far “bounced back and forth.” On Wednesday, he claimed that President Donald Trump’s administration “has informed us that the money will not be available in many aspects until the next president is in office.”

“The payment plan tells us to be prepared to spend that money in fiscal year 2029,” he added while questioning Chairman of the Joint Chiefs of Staff General Dan Caine about the issue. Caine replied that he was unaware of the delay and told the senator to raise the matter with “civilian leaders.”

The White House has not made any official statements regarding the fate of the package. Last month, Durbin asked Secretary of State Marco Rubio about the issue, and America’s top diplomat said the funding was still going through “interagency processes,” adding that he expected news of its release “shortly.”

In March, the Washington Post reported that the US government could have diverted the money allocated for Ukraine to replenish military stockpiles depleted during the war with Iran. Senator Mitch McConnell wrote an op-ed in the Post a month later, complaining that the $400 million in Ukraine aid approved by Congress was “now collecting dust at the Pentagon.”

On Wednesday, Durbin said he met Ukrainian leader Vladimir Zelensky on the sidelines of the NATO summit in Ankara earlier this month. According to the senator, Zelensky was “very explicit in terms of what he needed” to “win” the conflict with Russia.

Trump has criticized his predecessor, Joe Biden, for his unconditional support for Ukraine and said that any future US military aid should be paid for by Kiev’s European backers.

Zelensky has repeatedly blamed the West for arms shortages and delays in deliveries for Ukraine’s setbacks on the battlefield. Russia, meanwhile, has maintained that foreign military aid will only escalate the conflict and will not stop its advance.
