Congressional committees are swiftly investigating the attempted assassination of former President Donald Trump, focusing on security failures that allowed the shooter access to a nearby rooftop. The House Oversight Committee and the Senate Homeland Security Committee are leading the inquiries, scheduling hearings and requesting documents from the Secret Service and FBI. Lawmakers are questioning how the Secret Service's security protocols failed during the rally, prompting urgent briefings and public hearings to uncover the truth about the incident. Concerns about the security breach, along with calls for thorough investigations and accountability, have sparked bipartisan efforts in both chambers of Congress.
