Donald Harris was born and raised in Jamaica and moved to the US in the 1960s to study economics at the University of California, Berkeley. There, he met Harris' mother, Shyamala Gopalan Harris, during campus protests.
Gopalan Harris and Donald separated when Harris was 5 and divorced when she was 7. Casey Tolan wrote for Mercury News that Harris' mother had primary custody over her two daughters. The girls saw their father during vacations.
Tolan describes Donald as a "retired leftist Stanford economics professor from Jamaica who studied issues such as income inequality." The report also references a 1976 op-ed in the university paper that describes him as "too charismatic" and "a pied piper" to his students.
Per his Stanford page, Donald has worked extensively on the economy of Jamaica and has acted as a consultant to the country's government. He is a naturalized US citizen.
In a February 2019 appearance on the radio show The Breakfast Club, show host Charlamagne tha God asked Harris if she opposed marijuana legalization to which she responded, "Half my family's from Jamaica. Are you kidding me?"
In response to her answer, Donald published a comment in Jamaica Global Online saying, "My dear departed grandmothers (whose extraordinary legacy I described in a recent essay on this website), as well as my deceased parents, must be turning in their grave right now to see their family's name, reputation and proud Jamaican identity being connected, in any way, jokingly or not with the fraudulent stereotype of a pot-smoking joy seeker and in the pursuit of identity politics."
