Prosecutors said in a news release that 67-year-old Larry Russell Dawson of Antioch, Tennessee, was sentenced on March 20 in federal court in Washington. He has been ordered to receive mental health treatment.

Dawson had previously pleaded to a charge of assaulting, resisting, or impeding officers while using a deadly or dangerous weapon.

An officer shot Dawson on March 28, 2016, after he pulled out a BB gun that looked like a handgun at the checkpoint.

Dawson was also sentenced Monday to 90 days in prison for an earlier incident in which he disrupted Congress and failed to return to court.
