California Democratic Rep. Jim Costa of Fresno faced a formal review over allegations that he made unwanted advances toward young women working as congressional interns, according to records reviewed by NOTUS. A former House Democrat staffer filed a complaint in 2023 accusing Costa of inappropriate behavior during an incident in February 2020 when she was interning for a different lawmaker.
The Office of Congressional Conduct and the House Committee on Ethics investigated the allegations before jointly recommending dismissal of the matter. Both agencies concluded there was insufficient evidence to proceed with any formal action against the congressman, according to his office.
Costa has denied any suggestion of wrongdoing and pointed to the conclusions of ethics investigators who reviewed the complaint. His office emphasized that he fully cooperated with the review conducted several years ago. The OCC recommended dismissal, and the Ethics Committee unanimously voted to dismiss the matter, his office stated in response to inquiries from NOTUS.
What the Left Is Saying
Progressive Democrats have largely remained quiet on the Costa allegations, with some pointing to the official clearance of the matter as evidence that due process worked as intended. The dismissal by both the OCC and the House Ethics Committee means investigators found insufficient evidence to substantiate the claims, supporters note.
Costa represents a competitive Central Valley district that has shifted between parties in recent cycles. Some Democratic strategists argue that until formal findings emerge from credible investigations, members facing dismissed complaints should not face additional party discipline. The congressman secured re-election despite the allegations being known internally for years, suggesting voters had already weighed the information.
Others within the party have expressed broader concerns about workplace culture on Capitol Hill but stopped short of singling out Costa given the official dismissal. Party leaders have emphasized their commitment to addressing harassment in congressional workplaces through institutional reforms implemented over the past decade.
What the Right Is Saying
Republican critics have highlighted the timing of the allegations surfacing publicly amid a series of high-profile misconduct cases involving members of Congress. Former Reps. Tony Gonzales of Texas and Eric Swalwell of California both resigned last month over sexual misconduct claims, creating what conservatives describe as an uncomfortable spotlight on the Democratic conference.
Some Republican strategists argue that Costa's case illustrates broader questions about accountability in Congress. They note that ethics investigations often lack transparency and that dismissed complaints may not fully resolve questions about a member's conduct with staff and interns.
Conservative commentators have also drawn attention to Costa's past legal troubles, including an incident four decades ago when he apologized after being cited for soliciting a prostitute while traveling in a state-leased vehicle. Republicans argue such history is relevant context as voters evaluate current allegations, even those that resulted in dismissal.
What the Numbers Show
The House Ethics Committee has jurisdiction over sitting members and can recommend sanctions ranging from censure to expulsion, though such outcomes require full House votes. The OCC handles initial intake of complaints involving congressional employees but lacks independent enforcement authority against members themselves.
Costa was first elected to Congress in 2004 and has won re-election eight times. His district, California's 15th Congressional District, voted for President Trump in the 2024 election while also returning Costa to office, reflecting its swing-district characteristics.
The Office of Congressional Conduct reviewed approximately 150 workplace conduct matters annually in recent years, though only a small fraction involve sitting members. Ethics investigations that result in dismissal do not require members to face any formal consequences or public disclosure unless they choose to comment themselves.
Costa's past legal citation from four decades ago was reported by the Los Angeles Times and did not result in criminal charges. The congressman apologized at the time but has not faced similar allegations since, until the 2023 complaint that ethics investigators dismissed.
The Bottom Line
The Costa case represents one of several misconduct allegations against members that were ultimately dismissed due to evidentiary standards rather than cleared on the merits. Such outcomes leave questions unanswered for constituents while protecting members from formal consequences.
Costa remains in office and continues serving his district following the official dismissal by both investigative bodies. His office maintains that the ethics process speaks for itself, while critics argue the dismissal reflects procedural limitations rather than exoneration.
The broader pattern of misconduct allegations against members of both parties has intensified pressure on congressional leadership to strengthen workplace protections and transparency around ethics investigations. Any future complaints or developments in Costa's case would likely receive renewed attention given current scrutiny on Capitol Hill culture.
