There are many billionaires opposed to Trump— just some of them who have been actively speaking out against him and paying for recent ads opposed to him— Mark Cuban,  Warren Buffet, Koch Brothers (especially Charles Koch), George Soros, Michael Bloomberg, Steyer (named in this article was also head of Farollon Capital), Meg Whitman, Jeff Bozos (richest billionaire in the US), and William Dell. There are many more. On a different issue: Zuckerberg has opposed Trump, but he let 200 pro Trump workers at Facebook “embed” in the Trump cyber attack campaign force and hid much of this for a while. Some of these embedded workers are suspected of communicating with Russian hackers (question is “did they really know the hackers were Russian?” Were they suspicious that they might be Russian?).
