U.S. President Donald Trump on Monday filed a $15 billion lawsuit against The New York Times, alleging defamation and libel, and calling the newspaper a “mouthpiece” for the Democratic party.

In a post on Truth Social, Trump attacked the newspaper for being “a virtual ‘mouthpiece’ for the Radical Left Democratic Party,” while accusing it of making false statements about him, his family and business, without elaborating on the allegations.

The lawsuit suit has been brought in the state of Florida, Trump said, without providing further details.

Last week, Trump had threatened to sue the Times for its reporting on a sexually aggressive note and drawing that was given to the disgraced financier Jeffrey Epstein and appeared to have been signed by Trump.

The White House has denied that Trump was involved in the creation of the note, calling it a fabrication.

The Times did not immediately respond to CNBC’s request for comments.

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

In the post, he also mentioned his lawsuits against ABC News and anchor George Stephanopoulos, as well as Paramount over its 60 Minutes interview with the former Vice President Kamala Harris. Those cases ended in $15 million and $16 million settlement payment, respectively.

Trump has brought a $10 billion defamation suit against The Wall Street Journal for its article linking him to the Epstein note published.

The Journal’s article said that the letter purportedly written by Trump to Epstein in 2003 was among documents reviewed by criminal investigators who ultimately built criminal cases against Epstein and his convicted procurer, Ghislaine Maxwell, who reportedly solicited the letter from the president.
