Marc Short, Vice President Mike Pence’s chief of staff, was banned from the White House today after President Donald Trump criticized Pence for refusing to attempt to overturn the election, Bloomberg journalists first reported.

Short said Trump barred him from the grounds because the president is “blaming” him for advice he gave to Pence, according to RealClearPolitics reporter Philip Wegmann.

Short did not immediately respond to Insider’s request for comment.

Pence was set to oversee a joint session of Congress Wednesday in which the Electoral College votes, already certified by all 50 states, would be counted in a process that is usually nothing more than procedural.

Trump had urged Pence to challenge the results during the session, even though the vice president did not have the unilateral authority to do so.

Before the session, which was interrupted by a violent mob of Trump supporters, Pence released a statement saying he would not be following Trump's impossible demands.

"It is my considered judgment that my oath to support and defend the Constitution constrains me from claiming unilateral authority to determine which electoral votes should be counted and which should not," he said.

The president responded, criticizing Pence, in a tweet that has since been hidden by Twitter: "Mike Pence didn't have the courage to do what should have been done to protect our Country and our Constitution, giving States a chance to certify a corrected set of facts, not the fraudulent or inaccurate ones which they were asked to previously certify. USA demands the truth!"

The vice president is thought to be considering a presidential run in 2024, though his political ambitions could suffer due to Trump's criticism.
