DENVER (AP) -- One of the nation's most prominent election conspiracy theorists, MyPillow founder Mike Lindell, stuck by his false claims that the 2020 presidential election was stolen while testifying Monday during a defamation trial over statements he made about a former official for a leading voting equipment company. Taking the stand for the first time during the trial, Lindell denied making any statements he knew to be false about Eric Coomer, the former product strategy and security director for Denver-based Dominion Voting Systems. Among other things, Lindell accused Coomer of being "a part of the biggest crime this world has ever seen."
