So this is the application form:

Mamdani was born in Uganda to a Ugandan father and an Indian (Gujarati) mother. Which box would you tick?
Mamdani opted to tick "Black/African American" as well as "Asian", and at the "Other" box wrote "Ugandan".
I personally fail to see the problem. Given the constraints of these boxes, this seems to be the most accurate way of describing his ethnicity? Am I missing something here? Why is NYT presenting this as an issue at all?
Trump saying he's white despite him being orange seems like a bigger discrepancy.
