[Video below.] Sen. Bernie Sanders sharply criticized President Donald Trump’s glowing assessment of the U.S. economy during a Tuesday appearance on MSNBC’s “All In,” accusing the president of being “completely crazy and delusional, or just a pathological liar” for portraying current conditions as historic.

The remarks came after Trump, speaking on the Fox Business Network, praised the nation’s economic performance in sweeping terms.

“This is the greatest period of anything that we’ve ever seen. We had the greatest economy in the history of our country in my first term. I think we’re blowing it away. Now I think we have the greatest economy, actually, ever in history,” Trump said.

Responding to that clip, Sanders told host Chris Hayes that broader concerns about the country’s direction extend beyond the economy alone.

“Well, look, Chris, I think the American people understand with what’s going on in Minneapolis, Trump’s attacks on the media, universities. He is going after political opponents and through criminal actions, that we are moving into an authoritarian society,” Sanders said.

The Vermont independent then questioned Trump’s characterization of economic conditions, arguing that many Americans are struggling financially despite the president’s claims.

“In terms of I got to tell you, though, I seen that tape you just scrolled. You wonder whether Trump is completely crazy and delusional, or just a pathological liar. But the idea that anybody would believe that this is a great economy when 60% of our people are living paycheck to paycheck, when the cost of health care is going up, people can’t afford housing, people can’t afford their basic groceries, childcare system is dysfunctional, people can’t afford to go to college. And if this is the greatest economy in the history of the world, God help us.”
