A billionaire Facebook co-founder says he is giving $20 million to help defeat Donald Trump.
Dustin Moskovitz calls the Republican presidential candidate divisive and dangerous. And he says Trump's appeals to Americans who feel left behind are "quite possibly a deliberate con."
By contrast, he says, Democrats and their nominee, Hillary Clinton, are "running on a vision of optimism, pragmatism, inclusiveness and mutual benefit."
Moskovitz wrote about the contributions in a Thursday night posting on the website Medium.
He and his wife, Cari Tuna, are giving half of their $20 million to the League of Conservation Voters and to the For Our Future political action committee. The latter group is a get-out-the-vote effort in battleground states that is paid for primarily by labor unions and hedge fund billionaire Tom Steyer.
