Google founder donates $20mn more to organisation advocating against wealth tax

Sergey Brin has now donated more than $100 million to the campaign against California's proposed billionaire wealth tax. According to a newly filed California campaign finance report (first shared by Bloomberg), the Google co-founder has recently contributed an additional $20 million to political committee Building a Better California. His total donations now stand at $102 million. This makes him the largest financial backer of the campaign opposing Proposition 40. Proposition 40 is a ballot measure that would impose a one-time 5% tax on the wealth of California billionaires.​The filing shows Brin made the $20 million contribution on July 24. Building a Better California subsequently directed $10 million each to campaigns supporting Propositions 41 and 42, two competing ballot measures that could invalidate Proposition 40.
