A Democrat running to fill Rep. Katie Porter's (D-CA) soon-to-be-vacated House seat revealed he was cited for driving under the influence.

California state Sen. Dave Min took responsibility and expressed remorse for the incident, which he said took place Tuesday evening. Porter previously endorsed Min, who stressed he wouldn't let it distract his campaign.

CALIFORNIA REP. KATIE PORTER ENDORSES FORMER RIVAL DAVE MIN FOR HOUSE SEAT

"Last night I was cited for a misdemeanor for driving under the influence. My decision to drive last night was irresponsible. I accept full responsibility and there is no excuse for my actions," Min wrote on Facebook. "I am so deeply sorry. I know I need to do better. I will not let this personal failure distract from our work."

Additional details about the ordeal are not immediately clear. The Washington Examiner has contacted representatives for Min.

Min, a former law professor at the University of California, Irvine, previously faced off against Porter over the House seat back in the 2018 election cycle. He has served in the California state Senate since 2020.

Porter declared her candidacy for outgoing Sen. Dianne Feinstein's (D-CA) seat back in January. Porter's announcement came before Feinstein even announced she was retiring from the upper chamber. Min quickly entered the race to succeed Porter.

The seat was very competitive during the 2022 midterm elections, taking days for officials to determine the winner. Porter ultimately prevailed over her Republican foe 51.7% to 48.3%.

Porter hailed Min in her endorsement, claiming that he's "proven that he can win in this area while delivering on a progressive agenda."

He is facing a somewhat crowded field that features former Republican Assemblyman Scott Baugh and former Democratic Rep. Harley Rouda.
