John Yoo quoted by Fox Business, March 22, 2017
“The city of Berkeley should not be discriminating based on political views…I think then you’re going to start getting the courts involved and it’s going to look very skeptically at what this city is doing,” advised John Yoo. … Political disagreements are “not a valid reason to break a contract,” which, warns Yoo, may violate the Dormant Commerce Clause, which prevents cities from discriminating against outside companies, and there’s no legal exception for political disagreements.
