President Trump took to Twitter Friday morning to respond to fired FBI Director James Comey's upcoming book, calling Comey a "LEAKER & LIAR" and a "slime ball" who "should be prosecuted."
Comey's new book, "A Higher Loyalty," isn't officially released until Tuesday, but numerous news outlets, including CBS News, have obtained copies of the book ahead of time. In it, Comey describesdetailing the few months he was FBI director with Mr. Trump as president. Comey has claimed Mr. Trump asked for his loyalty, and to drop a matter involving former national security adviser , who misled Vice President Mike Pence and federal investigators about his contacts with Russian officials.
Mr. Trump fired Comey in May, eventually prompting Deputy Attorney General Rod Rosenstein to appoint special counsel Robert Mueller to lead the investigation into Russian election meddling and any ties to the Trump campaign.
On Friday, Mr. Trump claimed that "virtually everyone in Washington" thought Comey "should be fired for the terrible job he did — until he was, in fact fired. He leaked CLASSIFIED information, for which he should be prosecuted."
The president also claimed Comey "lied under oath."
In a follow-up tweet, Mr. Trump called Comey a "slime ball."
ABC News has an interview with Comey that is set to air Sunday night.
Kellyanne Conway, senior adviser to the president, also responded to Comey's book moments before Mr. Trump tweeted, in a gaggle with reporters at the White House.
Conway said Comey took "unnecessary, immature pot shots" at Mr. Trump's appearance in the book, likely a reference to Comey writing that Mr. Trump's hands were smaller than his, but not smaller than normal, and that Mr. Trump was shorter in person than he thought he would be.
