A federal judge on Friday ordered the U.S. Justice Department to disclose to House Democrats secret portions of the special counsel’s report on the Russia investigation, along with other materials concealed under grand secrecy rules, in a decision that pointed to the ongoing impeachment inquiry.

Chief U.S. District Judge Beryl Howell’s ruling delivered a victory to the House Judiciary Committee in its drawn-out legal battle for the full findings of former Special Counsel Robert Mueller III, who in March concluded his two-year investigation into Russian interference in the 2016 presidential election. In his summary of his office’s findings, Mueller reported that he uncovered no evidence that the Trump campaign conspired with the Kremlin, but he documented several episodes of possible efforts by the president to obstruct the investigation.
