Famous quotes containing the word high:
“From the beginning, the placement of [Clarence] Thomas on the high court was seen as a political end justifying almost any means. The full story of his confirmation raises questions not only about who lied and why, but, more important, about what happens when politics becomes total war and the truth—and those who tell it—are merely unfortunate sacrifices on the way to winning.”
—Jane Mayer, U.S. journalist, and Jill Abramson b. 1954, U.S. journalist. Strange Justice, p. 8, Houghton Mifflin (1994)
