A bipartisan group of senators, led by Democrat Richard Blumenthal and Republican Ron Johnson, expressed deep frustration and concern over the security failures that led to an assassination attempt on former President Donald Trump on July 13. Following a closed-door briefing with acting Secret Service Director Ronald Rowe, Blumenthal stated that the forthcoming interim report would shock and appall Americans with details of the Secret Service's and Department of Homeland Security's lapses. The investigation highlights a severe lack of preparedness and communication failures during the rally in Butler, Pennsylvania, where Trump was shot and a rallygoer was killed. Senators are pressing for more transparency and information from the DHS and Secret Service, with an interim report expected soon. Both parties emphasized the bipartisan nature of the investigation and the urgent need for improved security protocols to prevent future incidents.
