Five shocking admissions made by politicians

(CNN) After months of dodging allegations, Toronto Mayor Rob Ford admitted Tuesday he smoked crack cocaine about a year ago - probably, he said, during a "drunken stupor."

"Yes, I have smoked crack cocaine. But ... do I? Am I an addict? No," Ford said.

Ford's controversial admission of smoking crack adds to a long line of politicians who were forced to come clean to the public with their indiscretions.

Here are few shocking confessions made by politicians:

Former Senator and presidential candidate John Edwards admitted in 2008 to an extramarital affair with Rielle Hunter, a filmmaker hired by his presidential campaign. He denied being the father of her child until 2010.

4. New York Gov. Eliot Spitzer resigns over prostitution scandal

Former New York Governor Eliot Spitzer resigned from the empire state's top office after it was discovered he was involved in a prostitution ring. According to reports, Spitzer spent thousands of dollars over a period of several years as a patron of a high-priced prostitution service called Emperors Club VIP.

3. Mark Sanford admits to an extramarital affair with an Argentinian mistress: "I've been unfaithful to my wife"

2. Anthony Weiner resigns from Congress amid sexting scandal

Weiner would deny the accusations. In an interview with CNN's Wolf Blitzer, Weiner said he was hacked.

"Hundreds and thousands of times, just about every week, people have spam and hacking that goes on. It seems like I was a victim of that."

1. Bill Clinton: "I did have a relationship with Monica Lewinsky that was not appropriate."

Bill Clinton spent nearly six months denying the affair with the then 22-year-old White House intern, Monica Lewinsky. One of his best-known sound-bites denying the affair came at a White House press conference, with his wife Hillary Rodham Clinton standing by his side.

"I did not have sexual relations with that woman, Monica Lewinsky"
