 Story from AP, a threat from Iran prompted the U.S. Secret Service to boost protection around Donald Trump before Saturday's attempted assassination of the former president, though it appears unrelated to the rally attack, according to two U.S. officials. Upon learning of the threat, the Biden administration reached out to senior officials at the Secret Service to make them aware, the officials said, adding it was shared with the lead agent on Trump's protection detail and the Trump campaign that prompted the agency to surge resources and assets.
