Lawyers for President Trump want porn actress Stormy Daniels to pay them $340,000 in legal bills they claim they earned successfully defending Trump against her frivolous defamation claim.

The attorneys are due in a Los Angeles federal courtroom Monday to make their case that they rang up big bills because of gamesmanship and aggressive tactics by attorney Michael Avenatti, who represents Daniels.

Daniels, whose real name is Stephanie Clifford, alleges she had a one-night affair with Trump in 2006. She sued him earlier this year seeking to break a non-disclosure agreement she signed days before the 2016 election about the tryst as part $130,000 hush money settlement. Trump has denied the affair.

Despite the deal to stay quiet, Daniels spoke out publicly and alleged that five years after the affair she was threatened to keep quiet by a man she did not recognize in a Las Vegas parking lot. She also released a composite sketch of the mystery man.

She sued Trump for defamation after he responded to the allegation by tweeting: "A sketch years later about a nonexistent man. A total con job, playing the Fake News Media for Fools (but they know it)!"

U.S. District Court Judge S. James Otero ruled in October that Trump's statement was "rhetorical hyperbole" against a political adversary and was protected speech under the First Amendment. Trump is entitled to legal fees, Otero said.
