President Donald Trump has ordered a pause on military aid to Ukraine following a heated Oval Office exchange with Ukrainian President Volodymyr Zelensky on Friday, a White House official told CNN on Monday.

“The President has been clear that he is focused on peace. We need our partners to be committed to that goal as well. We are pausing and reviewing our aid to ensure that it is contributing to a solution,” the official said.

According to another official, the suspension applies to all military equipment not yet delivered to Ukraine. The decision, they added, is a direct response to what Trump perceives as Zelensky’s “bad behavior” during their meeting.

The pause could be lifted if Zelensky demonstrates a renewed commitment to negotiations aimed at ending the war. In the meantime, White House officials are seeking an acknowledgment from Zelensky regarding the recent breakdown in relations.
