Breaking news: Security threats at the White House Capitol Hill

WASHIONTON(AP) — Secret Service agents interrupted a live, televised White House press briefing Tuesday to evacuate journalists after a bomb threat was called in to police. No bomb was found, the Secret Service said.

President Barack Obama and other officials remained in the building during the evacuation, which only affected the James S. Brady Briefing Room. White House press secretary Josh Earnest, who was briefing reporters at the time of the evacuation, said later that Obama was never in any danger.

The evacuation came after a bomb threat related to the White House briefing room was phoned in to local Washington police, Secret Service spokesman Brian Leary said. Roughly 20 minutes later, uniformed Secret Service officers on the scene said an all-clear had been issued, and journalists were later allowed back into the White House, where the daily press briefing resumed.

Evacuations at the White House are rare, but not unprecedented. Last year, journalists and officials were temporarily evacuated after a fence-jumper made it inside the White House.

Yet Tuesday's incident was made more dramatic by the fact that it took place on camera during a live press briefing — the first such instance since the White House started allowing live television coverage of full press briefings in the 1990s.
