WASHINGTON (CNN/WOLO) – CNN says a lockdown at the White House has been lifted this morning.

Reports say a plane flew over a restricted airspace in the Washington, D.C. area, causing the lockdown.

Officials say the aircraft caused a “national event conference” to be convened. This is a group of senior national security officials across the agencies to coordinate and monitor the situation, according to a US defense official.

Again, reports say the lockdown has been lifted.
