Joint Base Andrews (JBA) lifted its lockdown Thursday morning, law enforcement sources told CBS News.
JBA reported via Twitter that there was an active shooter at the Air Force base early Thursday morning:

But an active shooter exercise was also scheduled at the base Thursday morning, prompting confusion about whether the reports were real.
Earlier, a U.S. Air Force spokesperson at the Defense Department confirmed the "active shooter" lockdown at Andrews.
"It's real," the Air Force spokesman told CBS News.
Later, conflicting reports from local police departments said no emergency units were dispatched to deal with an active shooter situation.
"There is so much confusion right now," a Prince George's County police department spokesperson told CBS News. "We don't know what's happening there. I can tell you we have no units dispatched to Andrews"
While testifying on Capitol Hill Thursday morning, Homeland Security Secretary Jeh Johnson noted to the Senate that he could be called out of the Judiciary Committee oversight hearing because of the "unfolding situation" at JBA.
JBA sent another tweet Thursday morning discussing the "ongoing" situation at the Malcolm Grow Medical Facility, reporting the presence of first responders on the scene.
