The Republican denies breaking rules or laws, but the move ensures that the Senate Ethics Committee cannot prosecute him in the scandal surrounding his affair with an aide.http://www.latimes.com/news/politics/la-na-ensign-resigns-20110422,0,6212238.storyNevada Sen. John Ensign, facing an ethics investigation stemming from his affair with a campaign aide, will resign Friday, his office announced.
The senator's decision was met with a collective sigh of relief — and little surprise — in his home state, where Ensign's scandals have dominated headlines for nearly two years.
Ensign, a Republican, had announced in March that he would not seek a third term in 2012, saying he wanted to spare his family from an "exceptionally ugly" campaign.
