President Donald Trump announced late Monday he was launching a $15 billion lawsuit against The New York Times in his latest attack on a major media company over its reporting and commentary on him.

The suit, filed in a Florida court, accuses the Times of being “a fullthroated mouthpiece of the Democrat Party” and cites a series of articles, including the paper’s front-page endorsement of Democratic nominee Kamala Harris in the lead-up to the 2024 election.

Trump said in a post on Truth Social the “degenerate” Times had “engaged in a decades long method of lying about your Favorite President (ME!), my family, business, the America First Movement, MAGA, and our Nation as a whole.”

“The New York Times has been allowed to freely lie, smear, and defame me for far too long, and that stops, NOW!” he added.

Trump’s suit names The New York Times Company, four of the publication’s reporters — Susanne Craig, Russ Buettner, Peter Baker and Michael S. Schmidt — and Penguin Random House, which published a book titled “Lucky Loser: How Donald Trump Squandered His Father’s Fortune and Created the Illusion of Success,” written by Craig and Buettner, that the legal filing calls “false, malicious, and defamatory.”

The suit alleges the reporting had harmed Trump’s “unique brand” and business interests, including his media company’s stock value, causing “reputational injury” worth “billions of dollars.”

Trump threatened only last week to sue the Times for reporting allegations he authored a sexually suggestive note in 2003 to disgraced financier and sex offender Jeffrey Epstein, who died by suicide in a New York jail cell in 2019. Trump has vigorously denied he wrote the note.

The Republican leader has launched a flurry of lawsuits against publications and media companies he has accused of being unfriendly and defamatory, including The Wall Street Journal, ABC and Paramount, the parent of CBS News.

In July, Paramount agreed to settle a $20 billion lawsuit filed by Trump over an interview with former Vice President Harris on CBS news program “60 Minutes” that the president said was deceptively edited, paying him $16 million.
