US court rejects petition challenging appointment of Robert Mueller

A U.S. appeals court on Tuesday rejected a challenge brought by an associate of Roger Stone, the indicted long-time advisor to President Donald Trump, to the legality of the Justice Department's 2017 appointment of Special Counsel Robert Mueller.

In doing so, the U.S. Court of Appeals for the District of Columbia Circuit upheld a lower court's decision to hold Andrew Miller in contempt for refusing to comply with a grand jury subpoena that was served on him by Mueller, who is investigating potential conspiracy between Trump's 2016 campaign and Russia.
