The White House press corps returned to the building's briefing room Tuesday after being evacuated following a "telephonic bomb threat."
White House Press Secretary Josh Earnest said after the briefing resumed that the room was carried out as a precaution taken by the Secret Service, adding that the threat was made before 2 p.m.
Earnest also said the briefing room was the only room evacuated within the White House complex. He also said that, while President Obama was on sight, he was not moved from the complex.
"Based on a threat that the Secret Service received from another law enforcement agency, the press room was evacuated, [and] they quickly searched and determined that it was safe and we all came back in the room," he also added.
At one point, dogs were searching the briefing room before guards appeared to be covering the cameras.
Earlier, two U.S. Senate office buildings were evacuated after reports of suspicious packages and a telephoned bomb threat, U.S. Capitol Police said .
Spokeswoman Kimberly Schneider said police cleared a room in the Dirksen building and the courtyard of the Russell building, both near the U.S. Capitol, and found nothing problematic.
There is no indication that both incidents are related.
