Following an assassination attempt on former President Donald Trump at a rally in Pennsylvania, President Joe Biden called for national unity and for Americans to 'lower the temperature' in political discourse. Biden's appeal was echoed by Trump, who indicated he will tone down his rhetoric and focus on bringing the country together in his upcoming Republican Convention speech. However, some Republicans, including Sen. Mike Lee, criticized Biden's call for unity as manipulative and insincere. The incident has sparked a broader debate on political violence, with House Speaker Mike Johnson calling for a full investigation into the security lapses. The FBI is treating the shooting as an act of domestic terrorism. The gunman, who was killed by the Secret Service, was identified as Thomas Matthew Crooks, a 20-year-old from Pennsylvania.
