A federal lawsuit by a former FBI agent in Denver offers an unusual glimpse inside the operations of the agency, where she accused several male agents of sexually harassing female counterparts, excluding them from important investigations and routinely skipping wire-tap assignments in cases run by female FBI agents.

Former FBI agent Danielle Marks claimed in the lawsuit filed on Thursday in Denver U.S. District Court that blatant sexual remarks became so commonplace that male agents repeatedly joked about how many zeroes would be on a lawsuit after making particularly offensive remarks.

Marks identified FBI Director James Comey as a defendant in the civil lawsuit filed on her behalf by Denver attorneys Charlotte Sweeney and Kaitlyn Wright.

Marks is asking to be reinstated as an FBI agent. She is also seeking back pay, compensatory damages and attorneys fees.

She has also filed a complaint with the FBI’s Office of Equal Employment Opportunity Affairs.

FBI spokeswoman Deborah Sherman could not be reached for comment on Friday.

Marks claims that she was “constructively fired” when she resigned under duress from the FBI in September 2014 after a year of discriminatory treatment.

environment at the (Metro Gang Task Force) became so hostile and intolerable that it began to affect Ms. Marks’s mental health,” the lawsuit says.

The lawsuit also raises questions about the professionalism of FBI agents who allegedly failed inexplicably to perform surveillance or wiretapping duties, presumably because Marks led the drug operations.

Marks became a FBI agent in 2010 and worked as a drug and gang officer in Baltimore, where she received “successful,” and “excellent” marks. She transferred to Denver in 2013, where she joined the MGTF, which is made up of Denver and Aurora police officers and federal agents.

Marks said she notified supervisors as early as September 2013 that fellow male agents refused to assist her with surveillance on her case even though it was the only open case in the office, the lawsuit says. She named three agents who “behaved inappropriately and made repeated sexual comments around Ms. Marks and other female employees.”

On 20 occasions, the agents failed to attend their surveillance shifts for her wiretap case. The only explanation she would receive is that they were “unavailable.” Agents would ask female agents to expose their breasts or allow them to perform sex acts on them, the lawsuit says.

In fact, the only FBI agents on the task force who had active cases were Marks and two other female agents. The male agents explained they were working a case that had closed in 2013. The male agents failed to come to work on days they were scheduled to work, the lawsuit says.

Her supervisor assured Marks that he would speak with the three FBI agents about the harassment and failure to work with her, but the agents’ behavior only got worse, the lawsuit says. They often made derogatory remarks about female FBI agents, including that they shouldn’t be in the FBI. Once, a FBI agent on the unit said he hoped another female agent would quit and “stay home in the kitchen.”

The agents would make lewd jokes about how one of the male agents was having an affair with a female prosecutor in the U.S. Attorney’s office.

Meantime, a supervisory agent was having an inappropriate sexual relationship with a female FBI agent, including openly sharing a hotel room during a work conference, the lawsuit says. The suit says the supervisor helped the woman get a position as secretary to Special Agent in Charge Thomas Ravanelle, who oversaw the Denver office and recently was transferred to the inspection division at the agency’s headquarters.

Agents would make sexually inappropriate remarks, look at Marks and the other female agent in the unit and say, “I wonder how many zeroes will be at the end of that lawsuit check,” the lawsuit says. It became so common that they would make a sexual comment and say, “Uh oh, add another zero.”

Marks was routinely excluded from drug operations involving the male agents and instead tasks were assigned to FBI agents who weren’t scheduled to work on the days of the operations and therefore couldn’t participate, the lawsuit says.

Agents also frequently excluded Marks and the other female agent in the task force on “rescue” missions. One officer said that duty should be “left up to the boys.”

When Marks resigned, her supervisor asked her not to disclose details about the behavior of the three male agents, pointing out that they were his friends, the lawsuit says. The supervisor had not interviewed Marks, the police sergeants and lieutenants on the unit who witnessed the “pervasive sexual harassment and misconduct.”

She said Ravanelle tried to coax her into staying in the FBI. He offered to transfer her to New York City. But Marks said she wished to stay on the task force and that the offending agents should be transferred instead, the lawsuit says.

“The FBI was motivated to discriminate against (Marks), in part, by its attitudes about women acting as special agents,” the lawsuit says.
