On Sunday night, Spike Lee won his first competitive Oscar, then made an acceptance speech that gained a standing ovation. But the events did not please at least one person apparently watching: President Trump. On Monday, he called Lee’s speech a “racist hit on your President.”

Lee opened his speech, after winning best adapted screenplay for “BlacKkKlansman,” by discussing slavery and his family’s experiences of it. “I give praise to our ancestors, who have built this country into what it is today along with the genocide of the native people,” he said.

“The 2020 presidential election is around the corner,” Lee said. “Let’s all mobilize. Let’s all be on the right side of history. Make the moral choice between love versus hate.”

Lee did not mention the president in his speech, but that call to action seems to have angered him. “Be nice if Spike Lee could read his notes, or better yet not have to use notes at all, when doing his racist hit on your President,” Trump said in a tweet in the early hours of Monday morning.
