WASHINGTON (AP) A federal jury on Monday convicted a New York Police Department veteran of assaulting an officer during the U.S. Capitol riot , rejecting his claim that he was defending himself when he tackled the officer and grabbed his gas mask.

Thomas Webster, a 20-year NYPD veteran, was the first Capitol riot defendant to be tried on an assault charge and the first to present a jury with a self-defense argument.

Webster, 56, testified that he was trying to protect himself from a rogue cop who punched him in the face. He also accused the Metropolitan Police Department officer, Noah Rathbun, of instigating the confrontation.

Rathbun testified that he didnt punch or pick a fight with Webster as a violent mob attacked the Capitol on Jan. 6, 2021, disrupting Congress from certifying Joe Biden s 2020 presidential election victory over then-President Donald Trump .

Websters jury trial was the fourth for a Capitol riot case. The first three defendants to get a jury trial were convicted of all charges in their respective indictments. A judge decided two other cases without a jury, acquitting one of the defendants and partially acquitting the other.

A grand jury indicted Webster on six counts, including a charge that he assaulted Rathbun with a dangerous weapon, a metal flag pole. Webster wasnt accused of entering the Capitol on Jan. 6.

WASHINGTON (AP) Jurors deliberated on Monday in the federal trial of a New York Police Department veteran charged with assaulting an officer who tried to protect the Capitol from an attacking insurrectionist mob last year.

Thomas Webster, a 20-year NYPD veteran, is the first Capitol riot defendant to be tried on an assault charge and the first to present a jury with a self-defense argument.

Jurors heard attorneys closing arguments on Friday and went home for the weekend about 30 minutes after getting the case. They returned to court on Monday morning.

Websters jury trial, which started April 26 , is the fourth for a Capitol riot case. The first three defendants to get a jury trial were convicted of all charges in their respective indictments. A judge decided two other cases without a jury, acquitting one defendant and partially acquitting the other after bench trials.

Webster, 56, is charged with assaulting Metropolitan Police Department Officer Noah Rathbun with a dangerous weapon, a metal flagpole, during the Jan. 6, 2021, riot.

Videos show Webster swing his metal flagpole at police, charge at Rathbun and then grab the officers gas mask with both hands.

Webster testified on Thursday that he was trying to protect himself from Rathbun after the officer punched him in the face. Webster also accused Rathbun of making a hand gesture that Webster perceived as an invitation to fight.

Rathbun testified that he didnt punch or pick a fight with Webster. Rathbuns body camera captured Webster shouting profanities and insults before they made any physical contact. Rathbun said he was trying to move Webster back from a security perimeter that he and other officers were struggling to maintain.

Prosecutors urged jurors to reject Websters self-defense argument and convict him of all six charges in his indictment.

Webster, who lives near Goshen, New York, retired from the NYPD in 2011. He served in the U.S. Marine Corps from 1985 to 1989 before joining the NYPD in 1991.

The violent Jan. 6 mob, loyal to then-President Donald Trump, stormed the Capitol in an attempt to overturn the 2020 presidential election, undercut the nations democracy and keep Democrat Joe Biden from replacing the Republican in the White House.

More than 780 people have been charged with riot-related federal crimes. The Justice Department says more than 245 of them have been charged with assaulting or impeding law enforcement.
