WASHINGTON (AP) — The Secret Service’s acting director has told lawmakers he considered it indefensible that the roof used by the gunman in the attempted assassination of former President Donald Trump was unsecured. He also says it’s regrettable that local law enforcement had not advised his agency that a gunman had been spotted on a nearby roof. Acting director Ronald Rowe also testified Tuesday that he recently visited the shooting site and laid down on the roof of the building where shots were fired in order to evaluate the gunman’s line of sight during the July 13 shooting in Butler, Pennsylvania.
