The House Ethics Committee announced Thursday it has established an investigative subcommittee to look into allegations of sexual misconduct against Rep. Ruben Kihuen, D-Nev.

“[T]he Committee unanimously voted on December 21, 2017 to establish an Investigative Subcommittee,” Ethics Committee Chairwoman Susan Brooks, R-Ind., and ranking member Ted Deutch, D-Fla., said in a statement Thursday. “Pursuant to the Committee’s action, the Investigative Subcommittee shall have jurisdiction to determine whether Representative Ruben Kihuen engaged in conduct that constitutes sexual harassment, in violation of House Rules, law, regulations or other standards of conduct.”

Brooks and Deutch said the committee will announce the members that will serve on the panel within the next week.

Multiple women have accused Kihuen of sexual harassment. In the wake of the allegations, Democratic leaders including House Minority Leader Nancy Pelosi, D-Calif., and Democratic Congressional Campaign Committee Chairman Ben Ray Lujan, D-N.M., called for Kihuen to resign.

The Nevada Democrat denied the allegations against him, but announced last week he would not seek re-election next year.

Sen. Al Franken, D-Minn., and Reps. John Conyers, D-Mich., and Trent Franks, R-Ariz., have all resigned due to allegations of sexual misconduct. Reps. Blake Farenthold, R-Texas, and Joe Barton, R-Texas, will retire at the end of their terms after facing allegations of inappropriate behavior.
