Two days after Guy Reffitt joined the rioters who stormed the U.S. Capitol on Jan. 6, federal officials said, he returned home to Wylie, Tex., and proudly told his family of his escapade. But by Jan. 11, when Reffitt learned the FBI was on to him, he changed his tune, according to an affidavit.

“If you turn me in, you’re a traitor and you know what happens to traitors … traitors get shot,” Reffitt, 48, said to his son and daughter, according to his wife, who recounted the conversation to the FBI, which did not name the relatives.

On Saturday, the FBI caught up to him. Reffitt, an oil worker with ties to self-styled militia and right-wing extremist groups, was arrested and charged with obstruction of justice for allegedly threatening his family and unlawful entry into the Capitol.
