Stormy Daniels is suing a number of police officers for $2 million (£1.5 million) over her arrest at a strip club last summer.
The porn star’s defamation lawsuit alleged that the officers conspired to retaliate against her due to her claims she had sex with Donald Trump.
According to the lawsuit, the four officers were supporters of the US leader who saw an opportunity to defame Daniels after they learned she planned to perform at Sirens men's club in Ohio.
Daniels, whose real name is Stephanie Clifford, was arrested in July on suspicion of inappropriately touching a female undercover officer. Two other club members were also arrested.
The 10-year-old law used to arrest Daniels means dancers at "sexually oriented" businesses are prohibited from touching customers and vice versa.
Prosecutors dropped charges against Daniels hours later, saying the law cited in her arrest applied only to those who regularly performed at the club.
The lawsuit was filed by Daniels' attorney, Michael Avenatti, a frequent critic of Mr Trump who at one time considered running for president
The officers "believed that Ms Clifford was damaging President Trump and they thereafter entered into a conspiracy to arrest her during her performance in Columbus in retaliation for the public statements she had made regarding President Trump", according to the lawsuit.
Officers also believed arresting Daniels would damage her credibility in any future remarks she made about the president, the lawsuit said.
The police department declined comment while an internal investigation of the city vice squad continues
Last year, city law chief Zach Klein called the law used to arrest Daniels "glaringly inequitable" because its applicability depends on how regularly the employee performs and should not be enforced.
He also said employees who touch police are not in violation because on-duty public officials are not legally considered patrons.
"We're aware of the lawsuit and are working to determine the best course of action for the city," said Meredith Tucker, a Klein spokeswoman.
The two dancers arrested with Daniels have filed a similar lawsuit.
