Clay, 06/04/69: Press surround heavyweight champion Muhammad Ali outside the Harris County Courthouse. (The slug "Clay" refers to Ali's former name, Cassius Clay, which was used in the court proceeding.) A Houston jury convicted Ali of draft evasion in June 1967. He appealed his conviction, arguing that he qualified for religious exemption as a conscientious objector. The United States Supreme Court sent the case back to the lower courts after the FBI admitted to wiretapping five telephone conversations involving Ali. On March 24, 1969, the Supreme Court ordered a hearing to determine if illegal government wiretapping played any part in Ali's conviction. The hearing began on June 1, with Justice Department attorneys presenting summaries of four wiretapped conversations. (The fifth was not admitted into evidence on the grounds that it might endanger national security.) Three were between Ali and Nation of Islam officials, including Elijah Muhammad. The fourth was between Ali and civil rights leader Dr. Martin Luther King Jr. Judge Joe Ingraham recessed the hearing without a ruling after five days, ordering the government to produce new evidence about the Ali-King conversation. The inquiry uncovered that the FBI recorded the exchange by wiretapping King, not Ali. And while FBI Director J. Edgar Hoover publicly maintained that the wiretap was installed on King's phone at Southern Christian Leadership Conference headquarters, testimony during the Ali hearing revealed that the wiretap was actually on King's home telephone. The unlawful surveillance and harassment of King by the FBI became the subject of a 1975 congressional investigation, leading to greater oversight of intelligence activities. The Supreme Court reversed Ali's conviction in 1971.
