During interviews with the FBI, the suspect arrested in the pipe bomb probe told investigators that he believed the 2020 election was stolen, providing perhaps the first indication of a possible motive for the bombs placed near the DNC and RNC headquarters, people briefed on the matter said. Cole spent hours with FBI investigators and made multiple statements, the sources said. Dan Bongino, deputy FBI director, told Fox News on Thursday that the FBI had interviewed the suspect at length, but didn’t elaborate. The FBI and the Justice Department declined to comment for this story.
