The Wall Street Journal is asking a judge to dismiss President Trump’s lawsuit against the newspaper over its Jeffrey Epstein reporting, calling the suit a threat to free speech.

“This case calls out for dismissal,” the Journal’s legal team wrote in a filing on Monday. “In an affront to the First Amendment, the President of the United States brought this lawsuit to silence a newspaper for publishing speech that was subsequently proven true by documents released by Congress to the American public.”

Trump sued the Journal this summer over a story it published about his alleged ties to Epstein and a birthday letter it reported he sent to the dead sex offender.

The president denies authoring the letter and has accused the Journal of defaming him with its reporting.

After the Journal’s story was published, however, the Epstein estate released a copy of the letter to the House Oversight and Government Reform Committee as part of a tranche of documents related to lawmakers’ Epstein investigations.

Lawyers for the Journal argued in their court filing this week the president was trying to suppress journalism that is unflattering to him.

“By its very nature, this meritless lawsuit threatens to chill the speech of those who dare to publish content that the President does not like,” the newspaper wrote, asking the judge to dismiss the suit.

The Journal is owned by billionaire media mogul Rupert Murdoch, an influential figure in business and politics with whom Trump has clashed for years.
