NEW YORK (AP) — The CEO of 21st Century Fox denounced racism and terrorists while expressing concern over President Donald Trump's reaction to the deadly violence surrounding a white nationalist rally in Charlottesville, Virginia.

James Murdoch also told friends in a personal email that he and his wife, Kathryn, will donate $1 million to the Anti-Defamation League.

Murdoch writes that the events in Charlottesville last weekend and Trump's response "concern all of us as Americans and free people."

"I can't even believe I have to write this: standing up to Nazis is essential; there are no good Nazis. Or Klansmen, or terrorists," Murdoch added. "Democrats, Republicans, and others must all agree on this, and it compromises nothing for them to do so."

Trump has put the blame for the violence on both white nationalists and those protesting the gathering last weekend, saying there were "very fine people" on both sides.

Murdoch is the son of the 21st Century Fox's co-executive chairman, Rupert Murdoch, a Trump ally who The New York Times reported recently dined with the president at the White House. The company is the corporate parent of Fox News Channel, which has given friendly coverage to the president.

The email was first reported by the Times Thursday.
