U.S. Sen. John Ensign, a Nevada Republican who is under an ethics investigation by the Senate, announced Thursday that he will resign his seat on May 3.
Ensign (pictured) had previously said he would not run for re-election in 2012 following revelations that he had an affair with a female aide who was the wife of another top aide, and that his parents subsequently gave money to the aides' family.
"While I stand behind my firm belief that I have not violated any law, rule, or standard of conduct of the Senate, and I have fought to prove this publicly, I will not continue to subject my family, my constituents, or the Senate to any further rounds of investigation, depositions, drawn out proceedings, or especially public hearings," Ensign said in a statement. "For my family and me, this continued personal cost is simply too great."FULL STORY
