At a time when corporate leaders have been highly critical of President Donald Trump over his response to deadly violence at a white nationalist rally in Charlottesville, Virginia, Berkshire Hathaway Chairman and CEO Warren Buffett has remained quiet, telling CNBC on Wednesday he tries not to mix business and politics.

"I'm not in the business of attacking any president, nor do I think I should be," Buffett said in a "Squawk Alley" interview.

Earlier this month, a deluge of CEOs distanced themselves from Trump in the wake of Charlottesville by leaving White House business advisory councils, which were later dissolved.

The tipping point for corporate America seemed to come Aug. 15 when the president angrily doubled down on his original comments about the deadly rally, and again blamed both the white nationalists and the counterprotesters for the mayhem.

Trump's critics felt he put neo-Nazis on the same moral footing as the demonstrators who gathered to denounce their racist views.
