Capitol Police had said that they received a bomb threat earlier in the afternoon, forcing them to evacuate several floors of the building.

The threat came as a Homeland Security hearing on airport screening was underway. The hearing was evacuated.

"Sad irony that our hearing on airport security in Homeland Security committee was interrupted by security threat," tweeted Sen. Claire McCaskill.
