Republican presidential candidate Donald Trump is returning on Saturday to the rural Pennsylvania location where he was nearly assassinated. As Donald Trump returns to Butler, Pa., for the first time since narrowly surviving an assassination attempt, current and former Secret Service agents are apprehensive about the potential for another security breach.
Secret Service spokesperson Anthony Guglielmi said in a statement before Saturday's rally that there had been "comprehensive changes and enhancements to our communications capabilities, resourcing and protective operations."
