Iran threat led to boosting of Trump security before shooting, US officials say

Secret Service and Trump campaign informed but alleged threat appears unrelated to assassination attempt

A threat from Iran prompted the US 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 US officials.

Upon learning of the threat, the Biden administration contacted 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. The officials spoke on the condition of anonymity to discuss sensitive intelligence matters.
