Nevada Rep. Ruben Kihuen, who is facing multiple sexual harassment claims, has announced he will not seek reelection to his seat in 2018. Kihuen, who former Sen. Harry Reid once called "a rising star in Nevada and the Democratic Party", unseated Republican Cresent Hardy in 2016 to become Nevada's first Latino congressman.

Nevada's 4th congressional district encompasses North Las Vegas and a large portion of rural central Nevada. The district was created after the 2010 Census, as the state added a congressional district due to rapid population growth. As recently as 1980, there was one at-large representative for the entire state. Kihuen is the 3rd person to represent the district, each of whom will have served only one term.

Hillary Clinton won the district by 5 points over Donald Trump in 2016. The seat is currently rated as 'Leans Democrat' for 2018.

Kihuen becomes the 40th House member, and 2nd from Nevada, to announce they aren't seeking reelection in 2018. Kihuen's colleague, Rep. Jacky Rosen, also in her first term, is attempting to unseat Sen. Dean Heller.
