Nixon administration Miller served as a
White House Fellow in 1968 and 1969, and was director of the White House Fellows from 1970 to 1971. During
Richard Nixon's administration, Miller worked as confidential assistant to Attorney General
John N. Mitchell for a year and a half, then was moved to the White House, where he worked with legal counsel
John Dean. In 2003, Miller recalled one of his early interactions with Dean involved a request that Miller "set up a safe house here in Washington for the use of the president," for what was intended to be "a completely covert White House operation." Miller said, "I knew at that point that I was going to have to leave. I just said to myself: 'This is insane.'"
