A federal appeals court in Washington ruled on Tuesday that the Department of Justice must hand over grand jury materials from former special counsel Robert Mueller's investigation to Congress.

A three-judge panel on the D.C. Circuit Court of Appeals upheld a federal judge's decision that the House's impeachment inquiry justified its request for the sealed documents.

"In short, it is the district court, not the Executive or the Department, that controls access to the grand jury materials at issue here," Judge Judith Rogers wrote in an opinion for the panel's 2-1 majority. "The Department has objected to disclosure of the redacted grand jury materials, but the Department has no interest in objecting to the release of these materials outside of the general purposes and policies of grand jury secrecy, which as discussed, do not outweigh the Committee’s compelling need for disclosure."
