A Mahopac man pleaded guilty for his role in the riot at the U.S. Capitol last year.
Court documents show that 52-year-old Anthony Vuksanaj pleaded guilty this week to parading, demonstrating or picketing in a Capitol building.
Authorities say they first learned about him when he was arrested in connection with a knife-point robbery in Westchester.
A search of cellphone records indicated it was used at the Capitol the day of the riot.
He will be sentenced in April and faces a maximum of six months of prison.
