American intelligence received information that Iran was interested in eliminating Donald Trump.
Thomas Crooks, 20, a Pennsylvania resident, may have been recruited by Tehran.
This version was voiced by CNN journalists, citing their informed sources.
The TV channel claims that Iran planned to assassinate the former US President. The relevant information was received by American intelligence services.
But reporters cannot say for sure whether this information was passed on to Trump's campaign headquarters.
The politician's entourage declined to comment on the issue of his security and suggested that CNN contact the US Secret Service directly.
The TV channel has information that Trump may have received warnings from the intelligence service about the planned assassination attempt.
He was advised to avoid holding events in open areas and other places where he could become an easy target for a killer.
However, CNN points out that the warnings were general in nature and did not contain any specifics.
Journalists also emphasize that to date the American side has no compelling evidence that Crooks is somehow connected to Iran.
