Official: No active shooter found at base
JOINT BASE ANDREWS, Md. - A law enforcement official says no active shooter was found at a military post outside Washington.
The law enforcement official was not authorized to discuss the matter by name and spoke on condition of anonymity.
Joint Base Andrews had been placed on lockdown Thursday morning after an active shooter was reported. The base is home to Air Force One and is about 20 miles from Washington.
An active shooter exercise had also been planned at the base, but officials said the situation became "real world."
The situation unfolded at a medical facility on the post. Joint Base Andrews issued a tweet telling all personnel at the base in Washington's Maryland suburbs to shelter in place.
