Factbox: A look at other political sex scandals

(Reuters) - Democratic Representative Anthony Weiner on Monday admitted having a number of online relations with women on the Internet, becoming the latest American politician snared in a sex-related scandal.

Here is a look at some of the others:

* Republican Representative Chris Lee of New York resigned in February after posting shirtless and flirtatious photos of himself on the Internet.

* Republican Senator John Ensign of Nevada, once seen as a potential presidential contender, stepped down amid an ethics committee probe into his affair with a former aide and attempted cover-up.

* Republican Senator Larry Craig of Idaho rejected calls to resign, but did not run for reelection in 2008 after he was arrested on charges of soliciting sex in an airport men's room.

* Republican Representative Mark Foley resigned after it was disclosed that he had sent sexually suggestive e-mails to former male pages.

* Former Democratic Senator John Edwards was indicted last week on charges of using nearly $1 million in illegal campaign funds to help cover up an extramarital affair during his 2008 run for the White House.

* Republican Senator David Vitter of Louisiana, in a stunning comeback, won reelection in 2010 -- despite having been earlier identified as a client of a prostitution service.

* Then-South Carolina Governor Mark Sanford likely ended his chances of ever running for president in 2009 when he tearfully admitted that rather than hiking the Appalachian trail as he had claimed, he was actually having an extra marital affair with a woman in Argentina.

* Democratic President Bill Clinton was impeached by the House in 1998 on charges of perjury and obstruction of justice stemming from his affair with a White House intern; but the Senate refused to remove him from office.
