MSNBC analyst and Washington Post columnist Eugene Robinson slammed President Trump's attacks on the media at a rally in Phoenix Tuesday night, calling his rhetoric "deeply disturbing."

“The thing about the speech last night was how sad and predictable it was," Robinson told "Morning Joe" co-host Joe Scarborough.

"I didn’t know he’d spend so much time on that. It was deeply disturbing and offensive the way he spoke of the media."

Trump railed against the media as "sick" and "crooked" during a rally at the Phoenix Convention Center, complaining that "they don't report the facts"

"These are sick people," Trump said. "If you wanted to discover the source of the division in our country, look no further than the fake news and the crooked media.

“It's time to expose the crooked media deceptions and to challenge the media for their role in fomenting divisions and yes, by the way, they are trying to take away our history and our heritage,” he added.

Trump said the media had mischaracterized his remarks about the violence at a white nationalist rally in Charlottesville, Va.

“They don't report the facts. Just like they don't want to report that I spoke out forcefully against hatred, bigotry and violence and strongly condemned the neo-Nazis, the white supremacists and the KKK,” Trump said. “I openly called for unity, healing and love, and they know it because they were all there.”

A recent NPR/PBS Newshour/Marist poll found that 93 percent of Trump's supporters do not trust the media, while 56 percent of Democrats in the same poll said they do.
