Vice President Mike Pence was ushered out of the Senate as the U.S. Capitol Complex went into lockdown due to an external security threat, while Trump supporters rioted outside the building.
A member of the Senate told NBC News that Vice President Pence and Sen. Charles Grassley, the president pro-tem, have been taken to a secure location. The Senate doors are closed and locked, and senators have been told to stay away from the doors.
Lawmakers had just begun the procedural process of counting the Electoral College votes and formally declaring President-elect Joe Biden the winner.
