A Maryland man who waved a Confederate flag attached to a lacrosse stick during the siege at the U.S. Capitol pleaded guilty on Tuesday to interfering with a police officer who was trying to disperse a crowd of rioters.

David Blair, 27, faces a maximum prison sentence of five years after pleading guilty to a felony charge of obstructing law enforcement during a civil disorder. Estimated sentencing guidelines in Blair’s case recommend a term of imprisonment ranging from eight to 14 months.

U.S. District Judge Christopher Cooper is scheduled to sentence Blair on July 13.

Blair was charged with assaulting a Metropolitan Police Department officer outside the Capitol during the Jan. 6, 2021, attack by a mob of Donald Trump supporters. Wearing a skull-themed face mask, Blair profanely taunted the officer and struck him with a wooden lacrosse stick adorned with a Confederate battle flag, prosecutors said. An officer’s body camera captured video of Blair waving the flag in front of a crowd that police were trying to disperse.
