The White House put top department officials on notice today that they are not allowed to spend money or use planes to help lawmakers travel on congressional delegation trips.

In a memo to the heads of executive departments and agencies, the White House's acting budget director said President Donald Trump asked him to convey that "under no circumstances during a government shutdown" will any federal funds or government aircraft — rented, owned or chartered — be used to support any congressional delegation "without the express written approval of the White House Chief of Staff."

The guidance comes after Trump made a public show Thursday of stopping House Speaker Nancy Pelosi and other Democrats from using military aircraft to fly to Afghanistan.
