Five years into retirement, Warren died due to cardiac arrest at Georgetown University Hospital in Washington, D.C., at 8:10 p.m. on July 9, 1974. He had been hospitalized since July 2 due to congestive heart failure and coronary insufficiency. On that same day, he was visited by Justices Brennan and Douglas, until 5:30 p.m. Warren could not resist asking his friends whether the Court would order President Nixon to release the sixty-four tapes demanded by the Watergate investigation. Both justices assured him that the court had voted unanimously in "United States v. Nixon" for the release of the tapes. Relieved, Warren died just a few hours later, safe in the knowledge that the Court he had so loved would force justice on the man who had been his most bitter foe.
