He asserted that Trump is unusual in his use of lies.

"We have had presidents in the past who have lied, there's no question about that," Bernstein said.

"But what we have never had is a president of the United States who uses lying and untruth as a basic method to promote his policies, his beliefs and his way of approaching the American people and engaging in the world," he contended.

Bernstein criticized Trump's comments, saying that the president's insistence that fake news is the enemy of the people has "echoes of totalitarianism."

"Uniquely, we have a president who does not believe in truth," Bernstein said. "This is far different from anything we have experienced."

"But, you know, Trump didn't invent this and we live in a time when truth is devalued in all kinds of institutions and we have now, this division, not just among our people, but through social media, through the press," he said.
