He used some of the money to make huge donations to conservative political candidates, including $55,000 to Virginia Attorney General Ken Cuccinelli and $10,000 to Rep. Michele Bachmann (R-MN). Both have given the donations away to (presumably real) charities, and there's no indication they knew the money was coming from a scammer.
He also liked to go to fundraisers and meet and greets, where he could shake hands and pose with Republican elites.
Thompson is not his real name. He's also alleged to be an identity thief, and his true identify and whereabouts are not known.
He was indicted Oct. 13 along with Blanca Contreras, who was an officer in his charity. She was arrested in North Carolina on Oct. 15.
