Former New Jersey governor Jim McGreevey stunned voters by announcing he was resigning because he had an affair with a man and was a "gay American." His wife dazed looking wife Dina Matos was at his side.
McGreevey never apologized to his wife at the news conference, although he asked for the "forgiveness and the grace of my wife." She has since sued McGreevey for fraud for not telling her he was gay before getting married.
Former House leader Newt Gingrich went public with his affair and subsequent divorce on the air by confiding in right wing Christian leader James Dobson during an interview. Gingrich also didn't bother with apologies. Instead, he noted that while his affair was going on while Republicans were impeaching Clinton, Gingrich pointed out that Clinton was impeached for lying under oath about the affair.
While Sanford, who as a congressman voted to impeachment President Bill Clinton over the Monica Lewinsky scandal, took seven days to apologize, it took Clinton seven months before he 'fessed up.
After initially claiming he "did not have sexual relations with that woman," Clinton famously declared, before later admitting, "I did have a relationship with Miss Lewinsky that was not appropriate. In fact, it was wrong. I misled people, including my wife. I deeply regret that."
It was Clinton's denial under oath, however, that brought the shame of impeachment on the president.
Despite the accusations of infidelity and lying, Clinton's popularity soared during his last years in office, and while he remains a polarizing figure, he is also immensely popular among Democrats. He has parlayed his prominence into a role as an international social activist.
