Paul Manafort lied to Robert Mueller

US Special Investigator Robert Mueller has accused the former campaign manager of Donald Trump, Paul Manafort, of lying to the investigators in the Russian investigation.

Manafort denies that he lied. Manafort signed a deal with justice in September. He confessed guilt in a few indictments and promised to cooperate with Mueller's investigation into possible Russian interference with the 2016 presidential election. Manafort's lie has not been disclosed.

Manafort was a member of the Trump campaign team as a leader for three months from March to August 2016.
