President Donald Trump suggested in a tweet on Friday that former FBI Director James Comey should hope that no recordings were made conversations between the two.

“James Comey better hope that there are no "tapes" of our conversations before he starts leaking to the press!” Trump tweeted.

Trump was apparently referring to three meetings he claims he had with Comey, who he fired on Tuesday. Trump said in an interview with NBC News that he and Comey had dinner at the White House and that Comey had told the president he wanted to continue in his position as director of the FBI.

Trump also said Comey had called him twice. During those conversations, Trump said he asked Comey if he was the subject of an FBI investigation. He said on all three occasions, Comey said he was not the subject of the investigation.

According to a New York Times story, Comey was asked by Trump during the dinner for his loyalty. Comey is said to have responded that he would offer honesty, but could not offer political loyalty.
