Former US President Donald Trump survived an assassination attempt in Pennsylvania. Weeks earlier, US officials received intel about an Iranian plot to kill him, but there's no link between this and the shooter, Thomas Matthew Crooks. Security was heightened after the threat was known, confirmed by national security sources. Trump and his ex-Secretary of State faced threats from Iran after Soleimani's 2020 killing. The Secret Service, along with other agencies, regularly gets new threat info. Trump's shooter was stopped at the rally by FBI agents. Questions are now raised about Secret Service security measures despite the shooter being swiftly neutralized.
