President Trump on Friday accused Rupert Murdoch and The Wall Street Journal of defaming him in an article about a lewd birthday greeting that the publication said Mr. Trump had sent to the disgraced financier Jeffrey Epstein decades ago. In a suit filed in the U.S. District Court for the Southern District of Florida, Mr. Trump said the article "falsely claimed that he authored, drew and signed" the note to Mr. Epstein. It asked for awarded damages "not to be less than $10 billion." The Journal published the article about the note on Thursday under the headline: "Jeffrey Epstein's Friends Sent Him Bawdy Letters for a 50th Birthday Album. One Was From Donald Trump." The article described a letter that appeared to be from Mr. Trump in a 2003 birthday album compiled for Mr. Epstein. The letter, which The Journal said it had reviewed, had a drawing of a naked woman on it with Mr. Trump's signature below her waist, alluding to pubic hair, the article said. "Happy Birthday " and may every day be another wonderful secret," The Journal said the note read. Mr. Trump has faced mounting criticism and pressure from his supporters over whether to release documents related to investigations into Mr. Epstein, who was charged with running a vast sex-trafficking scheme. Many of Mr. Trump's supporters were upset because they believed that Attorney General Pam Bondi was holding back some files related to the Epstein investigation.
