The Secret Service was already on high alert before Saturday's attempted assassination because of an Iranian threat against former President Trump.
Why it matters: Bipartisan fury has dominated the days since Trump was shot, and that was before the revelation his protective detail was already beefed up to account for an outside threat.
Human intelligence revealed the Iranian threat in recent weeks, CNN first reported. The Secret Service and Trump campaign were reportedly both warned of the threat.
Trump has been the target of Iran's ire since he ordered the assassination of Iranian general Qasem Soleimani in 2020.
The big picture: House Republicans are launching major investigations into the Trump assassination attempt.
House Oversight Committee Chair James Comer (R-Ky.) is set to subpoena Secret Service Director Kimberly Cheatle to appear at the panel's July 22 hearing, a committee spokesperson tells Axios' Juliegrace Brufke.
The Secret Service has vowedto cooperate with congressional investigations.
The bottom line: Donald Trump Jr. told Axios' Mike Allen today that his biggest question he wants answered about the events of Saturday is, "How did someone get that close for that long?"
"A guy does not get on a rooftop with a rifle where there's people, and now I've seen the videos for five minutes saying, 'There's a guy on a rooftop with a gun,'" he said.
"It literally doesn't happen. I've shot with these guys, I came from a competitive shooting background. ... That doesn't happen without a serious breach of something."
