Sean Curran previously served as the special agent in charge of President Trump's security detail and sprung to cover him on stage during the assassination attempt at a rally in Butler, Pennsylvania.

Curran was one of several agents who piled on top of Trump last July after a gunman opened fire on the then presumptive Republican nominee during a campaign rally in Butler, Pa.

Mr. Curran, a current agent, will take the helm of an agency that has been the focus of several investigations since the July assassination attempt against President Trump.
