The Secret Service put the White House‘s front lawn on a brief lockdown after a security incident near the front gate.
It appears that an unknown object was thrown over the fence on the North Lawn of the White House according to a source close to the situation.
The Secret Service quickly called a lockdown of the park and White House and closed off Pennsylvania Avenue.
Agents ushered press standing outside into the briefing room without providing further details at around 11:30 a.m. ET.
The Secret Service declared an all-clear order roughly 30 minutes later, allowing reporters back onto the North Lawn.
The White House has not provided additional details on what triggered the lockdown.
The lockdown occurred just days after the one-year mark of Trump’s assassination attempt at his Butler, Pennsylvania, rally.

The tragedy left Trump with a bloody ear, two men with life-altering injuries and father and firefighter Corey Comperatore dead.
There are still scores of questions left unanswered, including why 20-year-old Thomas Matthew Crooks shot the president-to-be.
The president’s security arrangements have bolstered in the aftermath of the assassination attempt, and another that followed just two months later at his Florida golf course.
This is a breaking story and will be updated.
