Special prosecutor Robert Mueller made his first significant move on Monday with the release of his first indictments and a surprise plea deal in the investigation into Russian meddling in the 2016 US presidential election. Legal experts said the court filings indicate Mueller is running a serious, deliberative, and far-sighted inquiry.

Former Donald Trump campaign chairman Paul Manafort and his former business partner Rick Gates turned themselves in to federal authorities to face charges related to the probe. Manafort was indicted on 12 counts related to hiding foreign payments, including one count of "conspiracy against the United States". A former foreign policy adviser to the Trump campaign, George Papadopoulos, has also pleaded guilty to lying to the FBI. 

White House press secretary Sarah Huckabee Sanders responded to the news on Monday by saying: "Today's announcement has nothing to do with the president. Has nothing to do with the president's campaign or campaign activity."
