Former Republican Congressman Denver Riggleman of Virginia appeared on MSNBC Thursday morning and said there were "a minimum" of seven white nationalist groups that were part of the January 6 insurrection at the U.S Capitol.

Riggleman is a former Air Force intelligence officer and former CEO of a National Security Agency contractor.

"We had a minimum of seven white nationalist groups that were involved in the siege," Riggleman said. "Seven, a minimum."

Riggleman now works with the Network Contagion Research Institute, which is affiliated with Rutgers University. He was referring to NCRI's report that lists the groups – most listed are actually white supremacist or neo-Nazi hate groups:

Proud Boys (White Supremacists) Oathkeepers (Anti-government) NSC131 (Neo-Nazi) New Jersey European Heritage Association (White Supremacists) Nick Fuentes and “Groyper Army" (Neo-Nazi) American Nationalist Party (White Supremacists) American Guard (White Supremacists)

NCRI says its mission "is to track, expose, and combat misinformation, deception, manipulation, and hate across social media channels."
