From the very end of Linda Greenhouse’s Rehnquist obit:
While the new chief justice found the confirmation process extremely disagreeable, he kept his composure and even his wry sense of humor. At one point, a Republican Senator, Orrin G. Hatch of Utah, commended him for his recent dissent in Wallace v. Jaffree, the case on silent prayer in the Alabama public schools. Senator Hatch observed that the Senate Judiciary Committee had voted for a constitutional amendment to allow such prayer. “What you have been labeled extreme for, is something a majority of this committee supports,” Senator Hatch said.
Justice Rehnquist smiled and shrugged. “We’re all extremists together,” he said.
