Trump lawyers ask judge to order Wall Street Journal owner to testify within 15 days. Key US politics stories from Monday 28 July at a glance

Donald Trump has asked a US court to order a swift deposition for billionaire Rupert Murdoch in the president’s defamation lawsuit against the Wall Street Journal.

The US president sued the publication and its owner over a 17 July article asserting that Trump’s name was on a 2003 birthday greeting for Jeffrey Epstein, who was later a convicted sex offender.

Trump’s lawsuit called the alleged birthday greeting “fake” and said the Journal published its article to harm the president’s reputation. In a court filing on Monday, Trump’s lawyers said Trump told Murdoch before the article was published that the letter referenced in the story was fake, and Murdoch told Trump he would “take care of it”.

“Murdoch’s direct involvement further underscores Defendants’ actual malice,” Trump’s lawyers wrote, referring to the legal standard Trump must clear to prevail in his lawsuit.
