Beryl Alaine Howell (born December 3, 1956) is an American lawyer and jurist who serves as a senior United States district judge of the United States District Court for the District of Columbia. She was district's chief judge from 2016 to 2023. As chief judge, she supervised federal grand juries in the District, including for the Mueller special counsel investigation into Russian interference in the 2016 United States elections and investigations into attempts to overturn the 2020 United States presidential election.[1][2]

In 2018, Howell struck down a regulation of the Federal Election Commission allowing dark money groups, certain nonprofit organizations engaged in political activities, to conceal their donors. She wrote that the regulation "blatantly undercuts the congressional goal of fully disclosing the sources of money flowing into federal political campaigns, and thereby suppresses the benefits intended to accrue from disclosure."[28] The Supreme Court later declined to review the decision.[29]

In that same year, Howell became the supervising judge for the grand jury working for special counsel Robert Mueller's investigation into Russian interference in the 2016 United States elections.[1] On October 25, 2019, she ruled in favor of the House Judiciary Committee, which had sought grand jury materials from the Mueller investigation, finding their impeachment inquiry into President Donald Trump to be a judicial proceeding.[30] Justice Department attorneys had previously asserted that congressional investigators had "not yet exhausted [their] available discovery tools,” arguments Howell said "smack of farce," as the administration had openly stated it would stonewall the investigation.[31]
