The White House was put under lockdown on Monday morning, according to reporters who cover the administration.
Journalists posted messages on social media announcing the lockdown as they were assembled in the White House press briefing room, where they have not had a briefing in nearly 100 days.
“We are literally locked in here,” wrote Megan Pratz, a reporter for Cheddar. “We can’t see much but Secret Service officers just ran across the lawn.”
The Secret Service posted a statement on Twitter minutes later saying the agency was “responding to an incident involving a suspicious package located on Pennsylvania Ave.”
Nearby pedestrian traffic routes were closed on Monday, the Secret Service added.
The White House did not immediately respond to requests for comment.
