Fox News remains a reliable supporter of the president, but the mogul’s WSJ has taken on Trump, triggering a legal battle.

NPR reports President Donald Trump has gotten personal in his defamation lawsuit against The Wall Street Journal and media mogul owner Rupert Murdoch. Trump is suing the paper after claiming on social media that he personally told Murdoch that a birthday card he allegedly sent convicted sex trafficker Jeffrey Epstein was a hoax,

Trump asked a federal judge to expedite a deposition of Rupert Murdoch in his $10 billion defamation lawsuit against The Wall Street Journal, citing his age.

Trump says he personally told his "very good friend Rupert Murdoch" that he had not sent a racy birthday greeting two decades ago to Jeffrey Epstein. Murdoch's Journal reported it anyway.

Murdoch’s lawyers will be able to bring out just where the Journal obtained the birthday card, as well as all the torrid details of the 15-year relationship between Epstein and Trump.

Donald Trump's legal case against the Wall Street Journal over a story about the U.S. president and Jeffrey Epstein could face hurdles, one of which is that it does not appear to comply with Florida state rules over the timing of defamation lawsuits,
