FULL HEARING: Secret Service holds Trump shooting investigation news conference | LiveNOW FOX

Senators are now accusing the Secret Service of trying to make local law enforcement into "a scapegoat" for the Trump rally shooting after its acting director testified this week about why gunman Thomas Matthew Crooks wasn’t spotted in advance in Butler, Pennsylvania.

Ronald Rowe, during his Capitol Hill testimony on Tuesday, appeared to blame local police for not seeing Crooks on top of the building from which he ultimately fired from.
