White House on lockdown for 2nd day in a row, Obama inside (PHOTOS)

The executive mansion has been locked down for the second time in less than 24 hours. The lockdown is due to an unknown situation, according to reporters in the press briefing room.

President Obama is believed to be inside the White House.

The closure on Wednesday morning came just after 11 a.m. local time.

On Tuesday, the White House was placed on a brief lockdown after a robbery suspect fleeing the scene jumped over the fence outside the Eisenhower Executive Office Building (EEOB, also known as the Old Executive Office Building) around 4 p.m. The lockdown was lifted about half an hour later.
