Roughly a week after Donald Trump started his second term as president, the U.S. military issued an order to three freight airlines operating out of Dover Air Force Base in Delaware and a U.S. base in Qatar: Stop 11 flights loaded with artillery shells and other weaponry and bound for Ukraine.

In a matter of hours, frantic questions reached Washington from Ukrainians in Kyiv and from officials in Poland, where the shipments were coordinated. Who had ordered the U.S. Transportation Command, known as TRANSCOM, to halt the flights? Was it a permanent pause on all aid? Or just some?

Top national security officials — in the White House, the Pentagon and the State Department — couldn’t provide answers. Within one week, flights were back in the air.

The verbal order originated from the office of Pete Hegseth, the secretary of defense, according to TRANSCOM records reviewed by Reuters.
