Twitter blocks racist 'Uncle Tim' slur against Sen. Tim Scott — but not til several hours after it started trending

Twitter took enforcement action on Thursday morning to block a racist trending topic that disparaged U.S. Sen. Tim Scott (R-S.C.) after he delivered the GOP response to President Joe Biden's first address to a joint session of Congress.

During his rebuttal Wednesday evening, Scott declared that "America is not a racist country" and condemned divisive rhetoric on race in politics. He said that he's experienced intolerance even from self-proclaimed liberals and progressives who have called him an "Uncle Tom" or used slurs like the n-word to attack him.

"I have experienced the pain of discrimination," Scott said. "I know what it feels like to be pulled over for no reason. To be followed around a store while I'm shopping."
