I am quoting Trump here:
"I didn't know she was Black until a number of years ago when she happened to turn Black"
Here is what the Trump campaign said in 2020:
"I'll note that Kamala Harris is a Black woman and he donated to her campaign," Trump campaign senior adviser Katrina Pierson said Tuesday in a call with reporters. "So I hope we can squash this racism argument."
So, really what this discussion is about is Trump's memory failure. He donated to Kamala Harris knowing she was Black, and then forgot.
You Trumpers are trying to defend Trump with convoluted theories about race, when this is about Trump having a brain fade.
For the record, when I voted for her back in the day in California, I didn't know she was Indian, she was the first Black California senator, IIRC.
