Congress moves quickly to investigate shooting at Trump rally

Lawmakers in the House and Senate are planning to investigate the assassination attempt on former President Donald Trump during a campaign rally in Butler, Pa. Trump was whisked off the stage by Secret Service agents after a gunman opened fire, leaving one rally attendee dead and two others injured. The gunman, identified as 20-year-old Thomas Matthew Crooks, was killed by the Secret Service. House Oversight Chairman James Comer and House Committee on Homeland Security Chair Mark Green are demanding documents and testimony from the U.S. Secret Service to understand how the gunman managed to access a rooftop near the rally. Senate Homeland Security and Governmental Affairs Committee Chair Gary Peters is also launching a separate investigation into the shooting. President Biden has pledged to review the Secret Service's planning and response to the incident. Some lawmakers are calling for enhanced protection for all major presidential candidates, while others are urging caution in judging the Secret Service's response until more information is available.
