In 1901, Congress informally requested Secret Service Presidential protection following the assassination of President [[William McKinley]]. The Secret Service assumed full-time responsibility for protection of the President in 1902, and two operatives were assigned full time to the White House Detail. President Roosevelt transferred eight Secret Service agents to the [[Department of Justice]], which formed the nucleus of what is now the Federal Bureau of Investigation (FBI). Triggered by the attack on President [[Harry Truman]], Congress enacted legislation that permanently authorized Secret Service protection of the President, his immediate family, the President-elect, and the Vice President (or the next officer to succeed the President) and the Vice President-elect. | In 1901, Congress informally requested Secret Service Presidential protection following the assassination of President [[William McKinley]].
