Elon Musk left his fate to Twitter to decide, and says he will now sell 10% of his Tesla stock to pay more taxes.

The amount of money billionaires are taxed has become a hot-button topic in Washington, with many lawmakers wanting higher taxes for the ultra-rich. In a Twitter thread Musk highlighted that his wealth is almost entirely tied up in stocks, since he doesn’t take a salary or bonus.

Musk put the issue to a poll, vowing to abide by the results.
