Facebook co-founder Dustin Moskovitz announced late Thursday that he will be donating $20 million to far-left groups as part of an effort to defeat Republican presidential nominee Donald Trump in the November election.

Recipients include organizations directly tied to Democratic presidential nominee Hillary Clinton, but also to radical left groups such as MoveOn.org and Color of Change, meaning that Moskovitz’s money will fund anti-conservative attacks beyond the election itself.

MoveOn.org and Color of Change were both listed as organizations devoted to suppressing freedom speech in a recent book by Wall Street Journal columnist Kimberly Strassel, The Intimidation Game: How the Left is Silencing Free Speech.

Strassel notes that MoveOn.org spread false information during the 2010 midterm elections about foreign donations to Republicans through the U.S. Chamber of Commerce, and that it has organized boycotts of companies, like Target, that dare to speak out about politics.

Likewise, Strassel documents Color of Change’s involvement in pressing ABC News to drop Andrew Breitbart from election night coverage in 2010, and boycotting advertisers on Fox News until Glenn Beck left the channel.

Moskovitz’s money will, no doubt, fund similar efforts in future. He still owns a significant stake in Facebook itself, which was recently accused of suppressing news from conservative outlets.

In an essay announcing the donations, Moskovitz wrote that he and his wife, Cari Tuna, “considered ourselves independent thinkers who respect candidates and positions from both sides of the aisle,” even though they have always voted Democrat.

“This cycle is different,” they say, because it is a “referendum” between optimism (Clinton) and fear (Trump):

The Republican Party, and Donald Trump in particular, is running on a zero-sum vision, stressing a false contest between their constituency and the rest of the world. We believe their positions, especially on immigration, which purport to improve the lives of Americans, would in practice hurt citizens and noncitizens alike. In contrast, the Democratic Party, and Hillary Clinton in particular, is running on a vision of optimism, pragmatism, inclusiveness and mutual benefit.

Moskovitz acknowledges in his essay that “a huge part of Donald Trump’s popularity is that he serves as a voice for those in the U.S. who have been left behind as the rest of the world has enjoyed enormous progress.” However, he says, the Democrat platform is a better vehicle for the aspirations of those left behind.

The article provides a partial list of the recipients of the money:

Hillary Victory Fund, the DSCC, and the DCCC

the League of Conservation Voters (LCV) Victory Fund

For Our Future PAC

MoveOn.org Political Action

Color Of Change PAC

several nonpartisan voter registration and GOTV efforts.

Moskovitz, who is worth over $10 billion, acknowledges that he may be criticized for using his money in an effort to sway the election: “This decision was not easy, particularly because we have reservations about anyone using large amounts of money to influence elections.”

However, he says he and his wife are motivated by “the deepest love for America, and for the world.”
