The Trump administration's decision to halt the delivery of some weapons to Ukraine, citing a Pentagon review of its dwindling stockpiles, was a long-held concern for Kyiv that finally became a reality.

The move "was made to put America’s interests first," a White House spokeswoman said, as U.S. munitions have been depleted in recent years.

Rep. Michael McCaul (R-Texas) said he is probing “very intensely” whether the Pentagon’s freeze is a breach of Ukraine aid legislation that Congress passed in 2024. He also argued the pause is coming “at the wrong time,” weakening Trump’s efforts to pressure Russian President Vladimir Putin to negotiate a peace deal with Ukraine.
