The U.S. Justice Department said the courts have no right to question its decision to drop the criminal case against former national security adviser Michael Flynn, even if a judge suspects the move is a political favor to an ally of President Donald Trump.

In the clash between General Michael Flynn’s lawyer Sidney Powell, and Judge Emmet Sullivan’s “friend” — former judge John Gleeson — Powell called out Gleeson’s claim on Wednesday that Sullivan should continue to prosecute Flynn even though the government has asked Sullivan to dismiss its case against him.
