The Justice Department has opened a criminal investigation into the origins of the Russia investigation, in the latest move by the White House to discredit the work of special counsel Robert Mueller. The move by Attorney General Bill Barr will give the Justice Department the power to subpoena witnesses and to convene grand juries and to file criminal charges. Congressmember Jerrold Nadler, who chairs the House Judiciary Committee, tweeted in response, “These reports, if true, raise profound new concerns that the Department of Justice under AG Barr has lost its independence and become a vehicle for President Trump’s political revenge.”
