Eric Schmidt is reportedly at odds with Google cofounder Sergey Brin over how a $100 million campaign against California’s billionaire tax is spent

Eric Schmidt and Sergey Brin, co-founders of Google, have found themselves on opposing sides of a political battle in California. The dispute stems from their $100 million campaign against Proposition 40, a billionaire tax initiative. The New York Post reported that Schmidt has become frustrated with Brin's co-founded coalition, as the group's efforts to defeat the measure failed.

Despite this setback, the coalition still endorsed several other propositions that were ultimately rejected. While Schmidt is reportedly only contributing to the defeat of the billionaire tax, his funding is also being used to oppose other measures. Brin, on the other hand, has contributed the majority of the funds to the coalition.

The split between the former tech giants is partly due to disagreements over the political effectiveness of their campaign and the use of their funds. Schmidt has pledged to oppose the billionaire tax, which could affect his substantial fortune of $58.1 billion.
