If Donald Trump's defamation suit doesn't settle, the discovery process could raise more questions about his ties to Jeffrey Epstein.

President Donald Trump filed a lawsuit Friday against media mogul Rupert Murdoch and the Wall Street Journal over the newspaper's reporting on ties between Trump and disgraced financier Jeffery Epstein.

President Trump has turned on his longtime on-again, off-again ally, Rupert Murdoch. He filed a $10 billion dollar lawsuit against Murdoch and his company Newscorp after the Wall Street Journal’s report on Trump’s alleged racy birthday letter to Epstein in 2003.
