The U.S. Secret Service is enhancing security measures for former President Donald Trump's campaign rallies after an assassination attempt. The Secret Service plans to surround Trump's podium with bulletproof glass, a precaution usually reserved for sitting presidents. This decision follows the resignation of then-Secret Service Director Kim Cheatle due to security lapses during the event. The Department of Homeland Security assists in establishing a permanent communication system to improve coordination among federal, state, and local law enforcement agencies.
