Rubén Jesús Kihuen Bernal (/ˈruːbən ˈkiːwɪn/; born April 25, 1980) is an American politician and former member of the United States House of Representatives for Nevada's 4th congressional district, serving from 2017 to 2019.

In December 2017, House Minority Leader Nancy Pelosi called on Kihuen to resign in response to sexual misconduct allegations against him by a female campaign staff member, as reported by BuzzFeed.

[2] His father Armando Kihuen was a laborer in Orange County, California, before moving to Las Vegas in the 1990s and becoming a middle school science teacher.

While in high school and college, Kihuen volunteered for the campaigns of Senator Harry Reid, Virginia Governor Mark Warner, and Houston Mayor Lee Brown.

Kihuen was first elected to the State Assembly in 2006, defeating incumbent Bob McCleary by a large margin (and with the support of the AFL-CIO) in a 3-way primary.

On March 28, 2015, Kihuen announced he was running for Congress in Nevada's 4th congressional district, seeking to defeat first-term incumbent Republican Cresent Hardy.

[1] In addition to the finance director's conversation with the DCCC operative, she also documented Kihuen's behavior in a series of March 10, 2016 text messages to a friend, and shared contemporaneous details of her departure with four other individuals at the time.

The woman, who asked to remain anonymous, told The Nevada Independent that he touched her thighs or butt in three separate incidents, and has sent her hundreds of sexually suggestive text messages.

[19] In November 2018, the House Ethics Committee formally sanctioned Kihuen, determining he "made persistent and unwanted advances towards women".

[21] Luján was joined just after midnight on December 2 by House Democratic Leader Nancy Pelosi, who called for Kihuen's resignation and declared that "the young woman's documented account is convincing, and I commend her for the courage it took to come forward".

[22] Nevada Democrats were quick to condemn Kihuen, although only Jacky Rosen, a fellow member of Congress, explicitly called for him to resign.

Aaron Ford, Kihuen's former leader in the Nevada State Senate, told reporters that he was "deeply disappointed and disturbed" by the allegations.

[20] After leaving Congress, Kihuen became the external relations director for Las Vegas' Immigrant Home Foundation (Fundacion Casa de Los Migrantes).
