President Trump said Thursday he was canceling an upcoming overseas trip for House Speaker Nancy Pelosi, D-Calif., due to the government shutdown, just a day after Pelosi threatened to cancel Trump’s State of the Union address later this month.

Trump’s move was an escalation of a fight between Trump and Pelosi over the ongoing shutdown and left her and other lawmakers who were slated to travel overseas stuck in the Capitol, as a bus that was scheduled to take them to their flight remained stalled outside a House office building.
