President Trump slammed Michael Cohen in a series of tweets on Friday.

President Trump on Friday asserted that his former attorney Michael Cohen "committed perjury on a scale not seen before" and cited a book Cohen "was pushing" as evidence.   Trump said in a series of tweets: "Wow, just revealed that Michael Cohen wrote a 'love letter to Trump' manuscript for a new book that he was pushing. Written and submitted long after Charlottesville and Helsinki, his phony reasons for going rogue. Book is exact opposite of his fake testimony, which now is a lie!"  "Congress must demand the transcript of Michael Cohen's new book, given to publishers a short time ago," Trump continued. "Your heads will spin when you see the lies, misrepresentations and contradictions against his Thursday testimony. Like a different person! He is totally discredited!" "Michael Cohen's book manuscript shows that he committed perjury on a scale not seen before," Trump added. "He must have forgotten about his book when he testified. What does Hillary Clinton's lawyer, Lanny Davis, say about this one. Is he being paid by Crooked Hillary. Using her lawyer?"  Mediaite notes that the source for the tweets appears to be a Daily Mail article about a book proposal Cohen circulated not long before the FBI raided his office.
