Reporters tweet their evacuation from White House press briefing room

Reporters were evacuated from the White House Tuesday afternoon after Secret Service agents interrupted spokesman Josh Earnest's daily press briefing. The reporters were escorted from the White House briefing room to the Old Executive Office Building, where the Vice President's office is. 

Just hours earlier, the Dirksen Senate Office building was given an "all clear" after the Capital Police recieved a bomb threat prompting the evacuation of the Senate building during a hearing on the Transportation Security Administration.
