A US Capitol Police source also said it is “still not known” what happened other than there was “a big slow-moving blob of something” on radar
| A “slow-moving blob” that may have been a flock of birds triggered a lockdown of the White House and caused the US Capitol to be placed on “restrictive access” Tuesday morning.
Senior national security officials across the agencies convened to coordinate and monitor the situation after the mysterious “blob” was seen on radar at the Capitol Police command center flying

just south of the National Mall, according to a law enforcement source.
Military aircraft were scrambled in response.
Initial assessments indicated that the “blob” was an unauthorized aircraft entering restrictive airspace, leading to the brief lockdown.
