California State Sen. Marie Alvarado-Gil is facing a civil lawsuit filed by her ex-chief of staff who alleges the senator forced him to do sexual favors while she was his boss and he suffered a back injury because of it. Alvardo-Gil, who represents parts of Eastern California and the Central Valley, recently changed her party affiliation from Democratic to Republican. Her former chief of staff, Chad Condit, filed the civil lawsuit in Sacramento Superior Court on Thursday. The lawsuit includes allegations of sexual harassment, discrimination, retaliation and violations of other state labor laws. Condit portrayed Alvardo-Gil as an erratic, controlling, sexually abusive authority figure. "This was a sex-based quid pro quo relationship of unwelcome advances and sexual behaviors coupled with punishment and flexing of power," Condit alleged. Condit worked for Alvarado-Gil first on her campaign when she ran as a Democrat for Senate District 4 in 2022. He became her chief of staff when she got elected and he was fired in December 2023. Condit, who is married, claimed he was pressured to perform oral sex on Alvarado-Gil when they traveled together for work. Condit said he did it to protect his job. Condit said during the final time, he suffered a back injury while performing oral sex on her in the seat of a car. As a result, Condit claims he suffered three herniated discs in his back and a collapsed hip. The complaint said Condit "was demeaned and made to feel empty and subordinate to his boss, a California state senator, with power over his career and livelihood." Condit said he began to reject Alvardo-Gil's demands for oral sex, using his back injury as an excuse. By August 2023, he said he made clear that her advances were not welcome. Condit said the senator began punishing him by threatening his job. Condit said Alvardo-Gil wrote him up and was issued a "bogus disciplinary letter with accusations of inappropriate behavior made by Alvarado-Gil against him." Condit had back surgery in October 2023 and said Alvarado-Gil fired him in December 2023. Condit claims prior to being fired, Alvardo-Gil threatened to hire his wife to get him to resign. "A disgruntled former employee has fabricated an outlandish story, presented without evidence, to get a payday," said Ognian Gavrilov, Alvardo-Gil's attorney. "We expect that the Senator will be fully cleared of any wrongdoing of these bogus, financially motivated claims."The California State Senate is also named in the lawsuit. "The Secretary of the Senate blindly accepted Alvarado-Gil's retaliatory actions and ratified her abuse of him," the lawsuit claims. "The Senate has not been served in this matter, but we are in discussions with counsel to assess next steps," secretary of the Senate Erika Contreras said in a statement. "The Senate takes all complaints incredibly seriously but is unable to comment on matters involving pending litigation.""Senator Alvarado-Gil is fully cooperating," said Jacqui Nguyen, press secretary for the California State Senate Republican Caucus. "This is a lawsuit regarding a former employee, so we need to allow the judicial process to go through its course." Condit is the son of former Congressman Gary Condit, who faced scrutiny in the high-profile death of Chandra Levy in 2001. KCRA 3 has reached out to Condit for comment, but did not receive a response as of Friday night.
