Wallace is deeply unpopular with pro-Trump hosts at Fox. “Chris hates Trump. He’s a passionate Democrat,” a pro-Trump Fox personality told me. Wallace has told interviewers in the past that he only registered as a Democrat to participate in local Washington, D.C., elections…

In private Trump blames Fox Corp. cochairman Rupert Murdoch for allowing segments like Griffin’s on the air. Sources who’ve spoken with Trump told me Trump thinks Murdoch wants him to lose. “Trump definitely thinks Rupert is not in his corner,” a Republican close to the White House said. Trump is not entirely wrong. Sources close to Murdoch said Murdoch has told people he thinks Trump will lose in November. Murdoch is thinking about how to steer his media empire into a post-Trump environment. “This is about business for Rupert,” one source said.

Earlier this summer Trump screamed at Murdoch during a phone call, according to a source briefed on their conversation. “They had a humongous blowup. Trump yelled that Fox’s coverage is unfair and the polling is fake,” the source said. “Rupert defended the network’s standards and polling.”
