Secret Service Orders Media to Clear White House
White House journalists and media crews were ordered by the Secret Service to clear the North Lawn of the building on Monday.
The security precaution happens on occasion in response to possible threats to the White House building, such as a suspicious package or a fence jumper.
Law enforcement officials are paying particularly close attention to security today as it is September 11, the anniversary of the 9/11 terrorist attacks.
President Donald Trump was at the Pentagon at the time of the security alert, delivering a speech recognizing 9/11.
NBC’s Peter Alexander noted on Twitter that a source told him that the White House lockdown was triggered after someone threw a yoga mat and a sign over the White House fence.
