Were United States v. Nixon and Zelman v. Simmons-Harris both US Supreme Court cases?
United States v. Nixon United States v. Nixon, 418 U.S. 683 (1974), was a landmark United States Supreme Court decision which resulted in a unanimous 8–0 ruling against President Richard Nixon, ordering him to deliver presidential tape recordings and other subpoenaed materials to the District Court. Issued on July 24, 1974, the ruling was important to the late stages of the Watergate scandal, when there was an ongoing impeachment process against Richard Nixon. "United States v. Nixon" is considered a crucial precedent limiting the power of any U.S. president to claim executive privilege.
Gravel v. United States Gravel v. United States, 408 U.S. 606 (1972), was a case regarding the protections offered by the Speech or Debate Clause of the United States Constitution. In the case, the Supreme Court of the United States held that the privileges and immunities of the Constitution's Speech or Debate Clause enjoyed by members of Congress also extend to Congressional aides, but not to activity outside the legislative process.
