Apparently Robert McNamara

McNamara's Tell
April 11, 2012

Sen. Barry Goldwater used to claim that whenever Ronald Reagan's CIA director, Bill Casey, lied while testifying before the U.S. Senate Select Committee on Intelligence, his deputy, Bobby Inman, would lean forward and pull up his socks to signal to the interrogators that Casey was not telling the truth. Apparently Robert McNamara, defense secretary under Presidents Kennedy and Johnson, used the same method on himself.
