Due to his role in Nixon's election campaign and his environmental advocacy, Morton expected to be appointed as Secretary of the Interior in 1969. However, he was passed over for the position in favor of a westerner. He had also been considered for Nixon's vice presidential running mate, but lost out to Agnew.
