Spygate is a conspiracy theory promulgated by President Donald Trump in May 2018 that the Obama administration had put a spy in his 2016 presidential campaign for political purposes. On May 17, 2018, Trump tweeted: "Wow, word seems to be coming out that the Obama FBI "SPIED ON THE TRUMP CAMPAIGN WITH AN EMBEDDED INFORMANT." In that tweet, he quoted Andrew C. McCarthy, who had just appeared on Fox & Friends repeating assertions from his own May 12 article for National Review.
