Protesters Assemble in Front of Trump Tower Awaiting the President

Melania and Ivanka Trump Criticized for Wearing High Heels

Charles Krauthammer said he was "shocked" that President Trump failed to explicitly name the racist groups who rioted in Charlottesville, Va. on Saturday.

"This is not a media story, it is a presidential story," he said of the protests over the planned removal of a Robert E. Lee statue in what was once called Lee Park.

He called it "shocking" that Trump "did not have the instinctive, reflexive, automatic response we'd expect from an American leader."

"The president did not do what was natural," he said, adding that most Americans were "utterly revolted by right-wing white supremacist neo-Nazi groups."

Krauthammer said Trump was too late in denouncing the violence in Thomas Jefferson's hometown by the time he named the groups on Monday.

"He had to read from a prompter the names of these groups," Krauthammer said.
