U.S. Rep. Ruben Kihuen announced on Saturday that he will not seek re-election, becoming the latest member of Congress to end his legislative career in the face of sexual harassment allegations.

The first-term Nevada Democrat, who is the subject of an ethics investigation in the House of Representatives, denied the allegations against him but concluded that the charges would distract from "a fair and thorough discussion of the issues" on the campaign trail.

"It is in the best interests of my family and my constituents to complete my term in Congress and not seek re-election," Kihuen, 37, said in a statement issued by his campaign committee.
