A Trump-supporting sheriff in California is facing a backlash from the MAGA faithful for claiming to have prevented an assassination attempt on Donald Trump over the weekend. You may remember Riverside County Sheriff Chad Bianco from his appearances on “Dateline’s” “To Catch a Predator” series back in the aughts, in which host Chris Hansen confronted alleged sex predators. But in the decade-plus since the show aired, Bianco’s extremism has become his claim to fame. In 2021, he was exposed as a former member of the extremist Oath Keepers militia; in touting his support for Trump earlier this year, he has said, “I think it’s time we put a felon in the White House.”
