An armed man approaching a White House checkpoint with a gun Friday afternoon was shot by a Secret Service agent after he ignored several orders to drop the weapon, the U.S. Secret Service said in a statement.

The incident prompted a lockdown of the White House that was later lifted. President Obama was not in the compound at the time of the incident, and Vice President Joe Biden, who was, was in a secure location.

The gunman has not been identified, but is in a critical condition, D.C. Fire and EMS said.
