A few days later, Nixon's press secretary, Ron Ziegler, described the event as "a third-rate burglary attempt". On August 29, at a news conference, Nixon stated that Dean had conducted a thorough investigation of the incident, when Dean had actually not conducted any investigations at all. Nixon furthermore said, "I can say categorically that ... no one in the White House staff, no one in this Administration, presently employed, was involved in this very bizarre incident." On September 15, Nixon congratulated Dean, saying, "The way you've handled it, it seems to me, has been very skillful, because you—putting your fingers in the dikes every time that leaks have sprung here and sprung there."
