Donald Trump has unleashed a public attack on Michael Cohen after his longtime personal attorney claimed the now-president had prior knowledge of the 2016 Trump Tower meeting between Donald Trump Jr. and Russian lawyer Natalia Veselnitskaya. The president, in turn, claimed Cohen was fabricating stories about him to take heat off himself. He tweeted Friday morning: "I did NOT know of the meeting with my son, Don jr. Sounds to me like someone is trying to make up stories in order to get himself out of an unrelated jam (Taxi cabs maybe?)" Trump mentioned taxis in reference to Cohen's links to New Yorks Taxi King Gene Freidman who was hit with a $1.34m judgment last month over claims he sexually harassed and later retaliated against a former assistant. Trump also speculated that Cohen's choice of lawyerformer special counsel to Bill Clinton, Lanny Daviswas influenced by the Clinton family. He said: "[Cohen] even retained Bill and Crooked Hillarys lawyer. Gee, I wonder if they helped him make the choice!"
