Republican Senators, led by Marsha Blackburn and John Barrasso, publicly confronted Secret Service Director Kimberly Cheatle at the Republican National Convention over the failure to prevent an assassination attempt on former President Trump. Lawmakers criticized Cheatle for security lapses that allowed the would-be assassin to approach Trump at a rally in Pennsylvania. Cheatle faced demands for resignation but has shown no intention of stepping down. The Secret Service has been under intense scrutiny for its handling of the incident, with growing calls for accountability and explanations regarding the security breach. Cheatle's explanations, including blaming a sloped roof for not deploying snipers, have sparked further outrage and disbelief among lawmakers and the public.
