and approved of over 100 bombings between 1905 and 1910, perhaps the largest domestic terrorism campaign in American history. BOI career Burns was considered well qualified to direct the Bureau of Investigation, and was friends with President Warren Harding's Attorney General Harry M. Daugherty. Burns was confirmed as Director of the Bureau of Investigation on August 22, 1921. He continued to run the Burns Detective Agency throughout his tenure as Director of the BOI. Under Burns, the Bureau shrank from its 1920 high of 1,127 personnel to 600 employees in 1923. Burns was responsible for hiring the first female special agents, Alaska P.

Burns was forced to resign in 1924 at the request of Attorney General Harlan Fiske Stone and on May 10, 1924, J. Edgar Hoover took over the position on a provisional basis. Burns Detective Agency and Teapot Dome In October 1924, the CPUSA's Daily Worker newspaper reported that Jacob Spolansky, recently resigned from the BOI, had joined the Burns Detective Agency, run by "Bill" Burns, "King of Dicks." Burns also became indirectly involved in the Teapot Dome Scandal, involving the secret leasing of naval oil reserve lands to private companies. In November 1927, Harry F. Sinclair went on trial in federal court for conspiracy to defraud the US in the leasing of the Teapot Dome naval oil reserve. At the request of Sinclair oil executive Henry Mason Day, Burns secretly hired a squad of 14 men from the William J. Burns Detective Agency to "investigate" his jurors. Day arranged for their compensation and received their
