WASHINGTON — The U.S. is halting some shipments of weapons to Ukraine amid concerns that its own stockpiles have declined too much, officials said Tuesday, a setback for the country as it tries to fend off escalating attacks from Russia.

Certain munitions were previously promised to Ukraine under the Biden administration to aid its defenses during the more than three-year-old war. The pause reflects a new set of priorities under President Donald Trump and came after Defense Department officials scrutinized current U.S. stockpiles and raised concerns.

The Pentagon review determined that stocks were too low on some weapons previously pledged, so pending shipments of some items won’t be sent, according to a U.S. official who spoke on condition of anonymity to provide information that has not yet been made public.

The Defense Department did not provide details on what specific weapons were being held back.
