WASHINGTON (Reuters) – A former U.S. Marine from Florida on Wednesday became the latest defendant associated with the Oath Keepers militia group to plead guilty to criminal charges related to the Jan. 6 U.S. Capitol riot.

Jason Dolan (45), from Wellington, Florida, has pleaded guilty in the conspiracy and obstruction of an official proceeding. Amit Mehta, U.S. District Judge, stated that Dolan was subject to a maximum sentence of 63-78 months under the federal sentencing guidelines. However, the court can deviate slightly from these guidelines.

Mehta stated that Dolan has already given “substantial aid” to investigators. Dolan would also be available for grand jury testimony, trial testimony, and interviews by investigators.

More than 600 individuals were arrested for riot-related offenses, according to Washington D.C.’s U.S. Justice Department.

As Congress was certifying Joe Biden’s victory in November, Trump supporters started a riot. Trump had earlier made a passionate speech declaring that his defeat was due to fraud.

According to public records, the Oath Keepers also had four defendants who pleaded guilty in January to riot charges. According toprosecutors, more than 50 defendants pleaded guilty in federal court to charges related to the Capitol Riot and many will be sentenced.

Prosecutors said that nine of the riot-related pleas to guilty were for felonies. At least forty of those guilty pleas related to riots relate to misdemeanors.

Dolan was charged with the crime along 17 Oath Keeper defendants.

Dolan was later indicted as part of a group of Oath Keepers who “forcefully entered” the Capitol. They eventually entered the Capitol’s Rotunda.
