Pence refuses to leave Capitol

While other leaders were taken to Fort McNair, Vice President Mike Pence refused to leave the Capitol. Unpublished photos Karl reviewed show Pence in a windowless garage with no furniture, where he remained for five hours.

For hours, Pence refused to get inside the vice presidential motorcade for fear that it would take him from the Capitol.

In one photo, Pence’s chief of staff Marc Short uses his phone to show him Trump’s tweet saying the vice president had no courage.
