WATCH: Jimmy Fallon Calls Out Trump as 'Shameful' for Waiting to Condemn White Supremacists After Charlottesville

The 'Tonight Show' host paused the jocularity to scold the U.S. president for failing to condemn racists in Charlottesville

A normally cheerful Jimmy Fallon struck a somber note in Monday’s “Tonight Show” when he criticized U.S. President Donald Trump as “shameful” for his two-day delay in condemning racists and white supremacists after the violent rally in Charlottesville, Virginia.

The late-night host said that he believed Trump’s condemnation finally came as a response to public pressure to do so. “It’s important for everyone, especially white people, in this country, to speak out against this,” Fallon said, his voice warbling with emotion. “Ignoring it is just as bad as supporting it.”

Speaking at the White House on Monday, Trump had said, "Racism is evil," and that the KKK, white supremacists and other hate groups were "repugnant to everything we hold dear as Americans."

Critics said Trump had waited too long to address the bloodshed, taking particular offense with his having stated initially that "many sides" were involved rather than explicitly condemning white supremacists.

At least one person was killed and 19 injured when a car, allegedly driven by nationalist James Alex Field, 20, plowed into a group of counter-protesters at a right-wing nationalist rally in Virginia on Saturday.

The rally was held by white nationalists and others who oppose a plan to remove from a Charlottesville park of a statue of Confederate Gen. Robert E. Lee.
