President Donald Trump's legal team wants to cast ex-national security advisor Michael Flynn as a liar if he accuses top White House officials of wrongdoing, according to The Washington Post. Flynn has pleaded guilty to lying to the FBI and is reportedly cooperating with special counsel Robert Mueller. If Flynn moves to accuse Trump or top aides of wrongdoing, the president's legal team plans to describe him as a liar who wants to shield himself, the Post reported.
