I tried looking that up too.
Same with people claiming that Kamala is on camera telling people that “she isn’t black”. Couldn’t find anything on either.
That said, I have to imagine as a young kid, she might have hid the fact that her dad was black. My wife grew up in an inner city area and has taught inner city her entire career. She has always said the bi-racial kids have it the worse. I can’t imagine there is a large Indian/Jamaican mixed community to feel “part of” anywhere?
