A retired Navy SEAL from Lisbon being questioned by the FBI about his activities during the insurrection at the U.S. Capitol has reportedly resigned as a contractor with an elite Navy training program.

The report about Adam Newbold was published by "Task and Purpose", whose website says it has a mission to "inform, engage, entertain, and stand up for active-duty military members, veterans, and their families".

Task and Purpose writer Jeff Schogol says Newbold told him he has resigned as a contractor with the Navy Warrior Challenge program. The FBI has contacted Newbold about what happened when he was at the Capitol during the siege on January 6, according to several reports.

Newbold told Task and purpose that the Navy Warrior Challenge program helps potential SEAL trainees prepare for the rigors of Basic Underwater Demolition/SEAL training.

Speaking to Task & Purpose, Newbold claimed he never went into the Capitol building. He said he tried to de-escalate tensions by placing himself between the pro-Trump mob and police – and disarming one rioter who wanted to use a wooden pallet to assault police officers, according to the report.

The former Navy SEAL recorded a Facebook video praising the actions of protestors on Capitol Hill.

Newbold said he later deleted the video after learning that one of the protestors, an Air Force Veteran, as well as a Capitol Police Officer and three other people, died during the riot.

At last report, Newbold said the FBI expressed interest in speaking with him again.

Newbold operates the Lisbon-based Advanced Training Group Worldwide, which according to its website, is comprised of “veteran special operators and intelligence community professionals” offering marksmanship training and consulting services to federal agencies, law enforcement, and military clients.

In 2015, ATG received $1.4 million from the Department of Defense for government services.

The Associated Press reports that a review of public records, social media posts, and videos shows at least 22 current or former members of the U.S. military or law enforcement have been identified as being at or near the Capitol riot.
