 In CN News, I'm Chip Hamlin. Federal investigators are trying to figure out why a would-be assassin attempted to take the life of former President Donald Trump at a rally in Pennsylvania. A Secret Service spokesperson confirms the agency relied on local police at the Trump rally in Butler, Pennsylvania on Saturday night to fill out part of its specialized units. Former Wake County Sheriff Donnie Harrison tells CN News, We're trying to do it. Do we need more training? Yes.
