President Donald Trump continued to fuel GOP accusations that an informant was embedded in his presidential campaign for political purposes, saying Tuesday that “a lot of people are saying” there were spies.

“A lot of people are saying they had spies in my campaign,” President Trump said during his wide-ranging comments in the Oval Office during a press spray of a meeting with South Korea’s President Moon Jae-in.

“If they had spies in my campaign, that would be a disgrace to this country,” Trump continued. “It would be very illegal aside from everything else. It would make probably every political event ever look like small potatoes so we want to make sure there weren’t. I hope there weren’t frankly.”

President Donald Trump listens to a question during a meeting in the Oval Office of the White House in Washington, May 16, 2018.

“If they had spies in my campaign, during my campaign for political purposes, that would be unprecedented in the history of our country,” he later added.

The president has seized on reports from the New York Times and Washington Post that the FBI sent an informant to meet with members of his campaign. The Times cited unnamed sources that these contacts were made only after the FBI had gathered information that the source’s targets had made suspicious contacts with Russians during the campaign.

The FBI has not confirmed that it used an informant and so far there is no evidence that was one embedded in the Trump campaign.
