Zuckerberg owns the Democratic Party leadership:

Senate Minority Leader Chuck Schumer, D-N.Y.Schumer, whose daughter works as a product marketing manager at Facebook, recommended Slaughter in late January, and the nomination was reportedly held up over background checks.

just two weeks ago, Schumer said that tech companies were working to police themselves, that Facebook was a “a very positive force,” and that he was “sympathetic” to the company’s situation. The Cambridge Analytica scandal dropped a week later.

Ugly.
