Warren Buffett: Elizabeth Warren should be 'less angry'

Berkshire Hathaway CEO Warren Buffett isn't a fan of Sen. Elizabeth Warren's (D-Massachusetts) populist style.

In a Monday interview on CNBC's "Squawk Box," Buffett argued that Warren should be "less angry and demonizing."

"I think that she would do better if she was less angry and demonizing. I believe in 'hate the sin but love the sinner,'" he said. "And I'm not sure that I've fully convinced Elizabeth Warren that that's the way to go."

Warren has enthralled liberals with her outspoken criticism of Wall Street, and progressive activists strongly urged her to run for president in 2016 against Democratic front-runner Hillary Clinton. Warren ultimately declared she would not run.

But Buffett, who supports Clinton's campaign, said Warren and other legislators should be more willing to embrace compromise.

"I think the whole nature of governing - particularly when you've got a divided government like we have now - is that you end up with bills that each side doesn't like but they like it better than doing nothing," he continued. "I mean, that's the way that government has to function. And it does not help when you demonize … the people you're talking to."

Warren's office did not immediately respond to a request for comment from Business Insider.
