The big winner in Donald Trump’s decision to fire Preet Bharara might be Rupert Murdoch

Since Election Day, Murdoch, now the executive chairman of Fox News, has personally nudged the network in a more pro-Trump direction, sources tell me. That effort included anointing Trump-friendly Tucker Carlson as the successor to Megyn Kelly as host in the 9 p.m. slot. Fox News staffers are also grumbling that segments now have to fit a “pro-Trump narrative,” one insider told me. Trump seems to be returning the goodwill: He asked Murdoch to submit names for FCC commissioner and tweeted praise for Fox News. He’s even taken policy ideas from the network. Now Murdoch may be poised to reap a much bigger win from a Trump administration action.

That’s because on Saturday Trump oversaw the firing of Preet Bharara, the U.S attorney for the Southern District of Manhattan, whose office is in the middle of a high-profile federal investigation of Fox News. The probe, according to sources, is looking at a number of potential crimes, including whether Fox News executives broke laws by allegedly obtaining journalists’ phone records or committed mail and wire fraud by hiding financial settlements paid to women who accused Roger Ailes of sexual harassment. Sources told me that prosecutors have been offering witnesses immunity to testify before a federal grand jury that’s already been impaneled.

Trump’s decision to fire Bharara ignited speculation that it was designed to blunt investigations like the Fox News probe.
