NYT:

A day after telling an audience of Black journalists in Chicago that Ms. Harris had “all of a sudden” decided to become “a Black person,” Mr. Trump posted a photo on his social media site of Ms. Harris dressed in a sari with a caption stating: “Your warmth, friendship, and love of your Indian Heritage are very much appreciated.”

Mr. Trump also amplified posts from Laura Loomer, a right-wing activist, who had posted copies of Ms. Harris’s birth certificate and had spread false accusations that Ms. Harris has lied about her race.
