President Trump on Thursday appeared to deny military aircraft to House Speaker Nancy Pelosi for an upcoming foreign trip, in response to her call to delay the State of the Union address amid the government shutdown.

In a stinging and curt letter, Trump said her trip has been “postponed.”

He wrote: “Due to the Shutdown, I am sorry to inform you that your trip to Brussels, Egypt, and Afghanistan has been postponed. We will reschedule this seven-day excursion when the Shutdown is over. In light of the 800,000 great American workers not receiving pay, I am sure you would agree that postponing this public relations event is totally appropriate. I also feel that, during this period, it would be better if you were in Washington negotiating with me and joining the Strong Border Security movement to end the Shutdown. Obviously, if you would like to make your journey by flying commercial, that would certainly be your prerogative.”
