Trump: If FBI spied on my campaign, 'bigger than Watergate!'

President Donald Trump lent credence today to reports that FBI informants had infiltrated his presidential campaign, saying that "if so, this is bigger than Watergate!"
Trump's comments came on the anniversary of Robert Mueller's appointment as special counsel to head the Justice Department probe into possible coordination between Russia and Trump campaign officials, an investigation Trump repeatedly has called a "witch hunt."
"Andrew McCarthy says, 'There's probably no doubt that they had at least one confidential informant in the campaign.' If so, this is bigger than Watergate!" McCarthy, a contributing editor at the National Review, wrote an article published last week headlined "Did the FBI Have a Spy in the Trump Campaign?"
