The shutdown feud between Speaker Nancy Pelosi and President Donald Trump escalated Friday after the California Democrat’s office revealed it had made commercial travel arrangements to continue an Afghanistan trip the president tried to cancel — but the administration leaked their plans.

There was already a security risk with the speaker and her congressional delegation continuing the overseas troop visit after Trump announced Thursday where they’d be going. But the heightened threat from Trump leaking the commercial travel plans led the delegation to call off the trip for now, a Pelosi spokesman said.

“After President Trump revoked the use of military aircraft to travel to Afghanistan, the delegation was prepared to fly commercially to proceed with this vital trip to meet with our commanders and troops on the front lines,” Pelosi spokesman Drew Hammill said in a statement.

“In the middle of the night, the State Department’s Diplomatic Security Service provided an updated threat assessment detailing that the president announcing this sensitive travel had significantly increased the danger to the delegation and to the troops, security, and other officials supporting the trip,” Hammill added. “This morning, we learned that the administration had leaked the commercial travel plans as well.”

The delegation has decided to postpone the trip “in light of the grave threats caused by the president’s action,” Hammill said.
