The U.S. Department of Justice has declined a request to re-investigate the 1965 assassination of Malcolm X. In a statement, the department said, “The matter does not implicate federal interests sufficient to necessitate the use of scarce federal investigative resources into a matter for which there can be no federal criminal prosecution.” Calls for a federal investigation have increased since a new biography on Malcolm X by the late scholar Manning Marable alleged that the actual killer is a man still living in Newark, New Jersey.
