Facebook's co-founder is donating $20 million to Democratic groups in hopes of stopping Donald Trump. If Donald Trump wins, the country will fall backward and become more isolated from the global community. Half of the $20 million would go to the League of Conservation Voters and to a super PAC called For Our Future, launched this year by labor groups and Tom Steyer, a billionaire environmentalist and top Democratic donor. Moskovitz and Tuna also plan to donate to Hillary Clinton's presidential campaign.
