Steve Ballmer vs. Sergey Brin

Ballmer and Microsoft cofounder Bill Gates were classmates at Harvard. Ballmer created a website called USAFacts.org for people to look up and understand where the government is spending money.

The richest immigrant in America, Brin has been an outspoken critic of Trump's immigration ban. Brin moved to the U.S. from Russia when he was 6 years old in the wake of anti-Semitism against his family.
