The judge in the case, U.S. District Judge Beryl Howell, gave the Justice Department until Oct. 30 to turn over the redacted portions of the grand jury material sought by the committee.
The Trump administration will likely appeal this ruling — including a request for a stay — to the US Court of Appeals for the DC Circuit.
The ruling is a key win for Democrats as the House Judiciary Committee begins to tackle articles of impeachment against President Trump.
Mueller found no evidence that Trump conspired with Russia in the 2016 election, but did not come to a finding on whether the president obstructed justice.
Even though the Mueller probe is separate from what the House Intelligence Committee is separately probing in relation to the president’s actions toward Ukraine, potential information in the Mueller grand jury documents could also help the committee craft articles of impeachment – specifically an article dealing with obstruction of Congress.
Democrats had requested that the department provide the material, which was redacted from Mueller’s report, as part of their ongoing impeachment inquiry against Trump.
Justice Department lawyers argued at a hearing earlier this month that House Democrats already had sufficient evidence from Mueller’s investigation, including copies of summaries of FBI witness interviews.
