A staff sergeant in the U.S. Air Force Reserve from Texas was arrested Wednesday on felony charges related to the Jan. 6, 2021, riot, where authorities say he pushed and grabbed police officers and called one officer a “traitor.”

Kyle Douglas McMahan, 41, of Watauga, was taken into custody in Dallas nearly three years after authorities say he joined the pro-Trump mob that attacked the Capitol wearing a red “Make America Great Again” hat with “God” written on it in black marker.

After the riot, his Google search history included: “Can I resign from the military if I do not want to serve an illegitimate president?” and “capitol terrorists identified,” according to court papers.

He faces felony charges of assaulting, resisting, or impeding officers and obstruction of law enforcement, as well as additional misdemeanor offenses.

There was no lawyer immediately named in the court docket. The voice mailbox was full for a number listed for McMahan and a person who answered the phone at a number listed for a relative declined to comment.

A Department of Defense database identifies McMahan as a current staff sergeant in the Air Force Reserve, according to court papers. The Air Force did not immediately respond to questions and a request for comment from The Associated Press.

Authorities say McMahan was seen on camera pushing back and forth against an officer outside a Capitol door before going into the building. During another encounter with law enforcement inside, prosecutors say he attempted to swat at an officer and grabbed an officer’s fingers, appearing to crush them in his hand.

Before he left the Capitol, he was captured on video telling one officer: “You’re a traitor,” according to court papers. Later that day, he was seen outside the Capitol wearing a green ballistics helmet and carrying an American flag.

Authorities say McMahan boasted on social media about being at the riot, writing: “For those that think we went in because of Trump is uninformed. We the people are the ones that need to rid our government of corruption, abuse and tyranny!”

He is among roughly 1,200 people who have been charged with federal crimes stemming from the riot that left dozens of police officers injured and halted the certification of President Joe Biden’s election victory. Those charged include dozens of former and active duty military or members of the reserve.

Nearly 900 defendants pleaded guilty or were convicted by a judge or jury after trials. Over 700 of them have been sentenced, with roughly two-thirds receiving prison sentences ranging from three days to 22 years.
