An assassination attempt on former President Donald Trump during a rally in Butler, Pennsylvania, has sparked widespread condemnation and calls for political unity. Trump, who was shot in the ear, is reported to be stable. The incident resulted in the deaths of one rally attendee and the alleged shooter, with two others critically injured. Politicians from both parties, including Ohio Gov. Mike DeWine and California Secretary of State Shirley Weber, have denounced the violence and called for a return to peaceful political discourse. The Secret Service has heightened security measures, and the FBI is investigating the incident as a potential act of domestic terrorism. The attempted assassination has amplified concerns about political violence in the U.S., with a YouGov poll indicating that a majority of Americans see it as a significant problem.
