A Texas man arrested for storming the US Capitol and assaulting police officers on January 6 also serves as a Republican Party precinct chair and has been an election poll worker in north Texas.

Mark Middleton, 52, was appointed as the chair of Precinct 14 in Cooke County in December, just a month after the presidential election, according to Chris McNamara, chairman of the Cooke County Republican Party.

A precinct chair is a low-level elected position in local party politics.

However, Middleton was not elected. He was appointed by a committee of local Republicans to fill the vacant precinct officer position.
