Sunday was the one-year anniversary of the tumultuous events in Butler, Pennsylvania – the first of two attempts on Trump's life during his presidential campaign last summer.
The Justice Department also confirmed in November it had thwarted an Iranian plot to kill Trump in the weeks leading up to the presidential election.
The Secret Service has admitted to suspending six agents without pay in February, but no one was fired, and the president has directed the Secret Service to give him "every bit of information" known about his two would-be assassins.
Also, weeks after the U.S. launched devastating airstrikes on Iran's nuclear facilities, an Iranian movement called the "Blood Covenant" has reportedly crowdfunded more than $40 million as a reward for assassinating President Trump.
The State Department is aware of threat, and Trump has made it clear that if Iran attempts an assassination, its country will be "obliterated."
Ken Valentine, who served 10 years with the Presidential Protection Detail, has told AFN he does not expect to learn much more about the Butler incident, but he believes the agency is reliable.

"I'm not sure whether I think so little of the Iranians or I just believe that the Secret Service will get the job done, but I have every confidence that the Secret Service that is with President Trump today will thwart any attack that's brought to bear upon the president," Valentine submits.
He thinks agents will protect the president or "die trying."
While signing an executive order imposing maximum pressure on Tehran, Trump said he has left instructions if something were to happen to him.
If Iran somehow carries out his assassination, he promises that "would be a terrible thing" for them, not himself, though he hopes the executive order will be unnecessary.
