From The Associated Press, June 2nd, 2010:

Lobbyist Larry Marchant admitted he had no proof to back up his allegation of a one-night stand with state Rep. Nikki Haley in 2008 and her campaign vehemently denied the allegation. The claim became the latest political drama for a state that was roiled when Gov. Mark Sanford made a tearful confession last summer to sneaking out of the country to rendezvous with an Argentine woman.

Earlier in the day, Marchant resigned from the campaign of Lt. Gov. Andre Bauer, who is competing with Haley for the GOP nomination in the June 8 primary.
