"Can you imagine people infiltrating our campaign? Is there anybody in this big, beautiful arena right now, that's infiltrating our campaign? Will you please raise your hand," he continued.

Trump made the comments during a rally for Rep. Marsha Blackburn (R-Tenn.), who's running to replace retiring Sen. Bob Corker Robert (Bob) Phillips CorkerHas Congress captured Russia policy? Tennessee primary battle turns nasty for Republicans Cheney clashes with Trump MORE (R-Tenn.).

Trump earlier in the speech attacked his former Democratic opponent Hillary Clinton and former President Obama for receiving campaign contributions from Blackburn's opponent, former Tennessee Gov. Phil Bredesen (D).

"Bredesen donated to the campaigns of Barack Obama Barack Hussein ObamaMichelle Obama and Jennifer Lopez exchange Ginsburg memories Pence defends Trump's 'obligation' to nominate new Supreme Court justice The militia menace MORE and Hillary Clinton. Crooked Hillary," Trump said to boos and chants of "Lock her up."

It was not clear who exactly the president was referring to on Tuesday night in his comment about infiltrating the campaign. But he has claimed numerous times without evidence that the FBI planted a mole in his campaign and sought to spy on his team for political purposes.

"With Spies, or 'Informants' as the Democrats like to call them because it sounds less sinister (but it’s not), all over my campaign, even from a very early date, why didn’t the crooked highest levels of the FBI or 'Justice' contact me to tell me of the phony Russia problem?" the president tweeted last week.

Gowdy said Tuesday that he believes the FBI acted properly with its use of an informant to speak with several members of Trump's campaign team.

"I am even more convinced that the FBI did exactly what my fellow citizens would want them to do when they got the information they got, and that it has nothing to do with Donald Trump," Gowdy said.
