The Department of Justice on Monday seemingly pushed back on the U.S. House’s claim that it needs grand jury materials from former special counsel Robert Mueller’s report to determine if President Donald Trump lied during the probe.

In a filing to the U.S. Court of Appeals for the D.C. Circuit, DOJ attorneys took issue with U.S. Chief District Judge Beryl Howell’s opinion saying that having access to the materials could “be helpful” to the House Judiciary Committee in considering witness testimony.
