George H.W. Bush and Jennifer Fitzgerald
Bush met Fitzgerald when she became his personal assistant in 1974. He was serving as special envoy to China at the time, but Fitzgerald stayed on, following Bush Sr. to his post at the C.I.A. and as Ronald Reagan's vice president. According to former U.S. diplomat Louis Fields, Bush and Fitzgerald shared a private cottage in Switzerland during an official visit in 1984 (all the while, Barbara Bush was out promoting her book C. Fred's Story, about the Bush family dog). Much to the frustration of the Clinton camp, this story never received nearly the coverage of the 42nd president's numerous affairs. That's not for lack of trying, either: In a May 1992 interview with Vanity Fair, as her husband was being dogged by allegations surrounding his affair with Gennifer Flowers, Hillary Clinton was quick to remind everyone that President Bush had his own Jennifer.
GHWB never seemed to mind when a Clinton was disparaging him. He should have become a Democrat when he moved to TX; he would have been happier with the Dems.
