'If they had spies in my campaign, that would be a disgrace to this country': Trump

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.”

“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.

The president rebuffed ABC News' question about whether he continues to have confidence in Deputy Attorney General Rod Rosenstein, who on Sunday said the DOJ would look into whether there was any improper activities related to the Trump campaign after the president ordered DOJ probe the issue.

“What is your next question, please,” Trump said, passing over the question. “I have the president of South Korea here. He doesn't want to hear these questions, if you don't mind.”

On Sunday, Trump took to Twitter to issue a "demand" that the DOJ "look into" whether there was any improper surveillance of his campaign "for political purposes."

Later Sunday, Rosenstein issued a statement saying, “If anyone did infiltrate or surveil participants in a presidential campaign for inappropriate purposes, we need to know about it and take appropriate action."

Following the weekend tweet, President Trump met on Monday with Rosenstein and FBI Director Christopher Wray. Despite the timing of the meeting the day after his tweet demand, the president said Tuesday that the meeting was “very routine."

Senate Democratic Leader Charles Schumer is among critics who have called it highly inappropriate.

Speaking of the alleged informant, the president said he’s read in news reports that “some person got paid a lot of money” and “that is not a normal situation, the kind of money you are talking about.”

“I think the Department of Justice wants to get down to it and Congress does so hopefully they will all be able to get together,” Trump said. “General Kelly will be setting up a meeting between Congress and the various representatives and they will be able to open up documents, take a look and find out what happened.”

Democrats have raised objections to that meeting as well – demanding to be included and questioning whether Trump and Kelly would be allowed to review classified information about the Mueller investigation that include the identify of any informant.
