Question: What was the Washington Post's circulation the year Kavanaugh was nominated to the US Court of Appeals for the DC Circuit? Passage:Kavanaugh graduated from Yale University, where he joined Delta Kappa Epsilon fraternity. After graduating from Yale Law School, he began his career as a law clerk and then a postgraduate fellow working under Judge Ken Starr. After Starr left the D.C. Circuit to take the position as head of the Office of Independent Counsel, Kavanaugh followed and assisted him with various investigations concerning President Bill Clinton, including the drafting of the Starr Report, which urged Clinton's impeachment. After the 2000 U.S. presidential election (in which he worked for the George W. Bush campaign in the Florida recount), he joined the administration as White House Staff Secretary and was a central figure in its efforts to identify and confirm judicial nominees. Kavanaugh was nominated to the U.S. Court of Appeals for the D.C. Circuit by President Bush in 2003. His confirmation hearings were contentious; they stalled for three years over charges of partisanship. He was ultimately confirmed to the D.C. Circuit in May 2006 after a series of negotiations between Democratic and Republican U.S. Senators. An evaluation of Kavanaugh's appellate court decisions in four separate public policy areas was performed by two law professors for the Washington Post. It found he had the most conservative overall voting record on the D.C. Court between 2003 and 2018.
