Brett Michael Kavanaugh (born February 12, 1965) is an American lawyer and jurist serving as an associate justice of the Supreme Court of the United States. He was nominated by President Donald Trump on July 9, 2018, and has served since October 6, 2018. He was previously a United States circuit judge of the United States Court of Appeals for the District of Columbia Circuit.

Kavanaugh studied history at Yale University, where he joined the Delta Kappa Epsilon fraternity. He then attended Yale Law School, after which he began his career as a law clerk working under Judge Ken Starr. After Starr left the D.C. Circuit to become the head of the Office of Independent Counsel, Kavanaugh assisted him with investigations concerning President Bill Clinton, including drafting the Starr Report recommending Clinton's impeachment. He joined the Bush administration as White House staff secretary and was a central figure in its efforts to identify and confirm judicial nominees. Bush nominated Kavanaugh to the U.S. Court of Appeals for the D.C. Circuit in 2003. His confirmation hearings were contentious and stalled for three years over charges of partisanship. Kavanaugh was confirmed to the D.C. Circuit in May 2006.
