Mr Manafort, 69, has pleaded not guilty to all charges.
In a reference to the special prosecutor who is heading-up the Russian Federation probe, the president added: "Bob Mueller is totally conflicted, and his 17 Angry Democracts that are doing his dirty work are a disgrace to the United States of America!"
