In 1998, McCain was chastised for reportedly making an off-color joke at a Republican fundraiser about President Clinton's daughter, Chelsea, saying "Why is Chelsea Clinton so ugly? Because her father is Janet Reno." McCain later apologized to President Clinton and Clinton accepted his apology. 
McCain has acknowledged engaging in extramarital affairs upon returning from Vietnam. While he was in Vietnam, his wife Carol had been severely injured in a car accident. Upon returning home in 1973, McCain found his wife to be very different from when he had married her. He soon began engaging in extramarital affairs and in 1979, he met Cindy Hensley. A year later, McCain sought a divorce from Carol and a month after that, he married Cindy. McCain has accepted full responsibility for the divorce and remains on good terms with Carol, who said in 2000, "I'm crazy about John McCain and I love him to pieces."  Carol has supported McCain in every election of his career, including his run for the presidency in 2000.
Joan Molinaro, Bruce De Cell, Grace Godshalk and Peter Gadiel of "9/11 Families for a Secure America" accused McCain of "screaming at them" during a chance encounter with McCain when they criticized his proposed immigration reform bills, which they felt were not strict enough in stopping terrorists from crossing the southern border.
