Karen McDougal, the former Playboy model who has said she had a 10-month affair with President Donald Trump around 2006, sued the Fox News Network for slander Thursday.

Trump has denied the affair repeatedly.

In McDougal's complaint, personal injury lawyer Eric Bernstein quoted Tucker Carlson's comments on a December 2018 episode of his show, "Tucker Carlson Tonight."

Carlson said two women had "threatened to ruin" Trump's career and "humiliate his family" if he didn't give them money, according to the complaint. Carlson described this as a "classic case of extortion." He showed a photo of McDougal onscreen, according to the complaint.

In a statement reported by The New York Times, Fox News said it would "vigorously defend Tucker Carlson against these meritless claims."

McDougal filed suit in Manhattan's New York County Supreme Court, but Fox News attorney Shawn Patrick Regan of Hunton Andrews Kurth quickly filed a notice of removal to the U.S. District Court for the Southern District of New York.

Regan declined to comment Thursday.

McDougal was paid $150,000 to turn over the rights to her story of any affair in a 2016 deal with American Media Inc., the parent company of the National Enquirer. Trump's representatives have denied the affair.

The payment later became part of an investigation involving former Trump attorney Michael Cohen, who was sentenced to three years in federal prison for tax evasion, lying to Congress and campaign finance violations related to the AMI deal.

AMI entered into a nonprosecution agreement with prosecutors in the Southern District of New York after its role in suppressing McDougal's allegations came to light, the U.S. Attorney's Office announced in late 2018.

In McDougal's complaint, Bernstein wrote that no one involved in the payment indicated that she extorted Trump.

The goal throughout the payment process was to prevent the affair allegation from influencing Trump's ongoing presidential campaign, Bernstein wrote. The timing of McDougal and Trump's alleged affair coincided with the early stages of his marriage to Melania Trump and the birth of their son Barron.

Bernstein cited a recording Cohen made of Trump discussing the payment.

"Trump can be heard voluntarily suggesting a cash payment to McDougal without any suggestion of extortion or threats," Bernstein wrote.

Regan, the Fox News lawyer, declined to comment Thursday. In a statement reported by The New York Times, Fox News said it would "vigorously defend Tucker Carlson against these meritless claims."

Bernstein did not immediately respond to a request for comment.
