【Watch Friends】

Dustin Moskovitz,Watch Friends one of the co-founders of Facebook, is going all in on the 2016 election with a humongous $20 million donation to a handful of Democrat groups, including some directly backing Hillary Clinton, in an effort to fend off GOP candidate Donald Trump.

Moskovitz and his wife, Cari Tuna, posted an explanation for their donations in a post on Medium, saying this is the first time they have either endorsed a presidential candidate or donated to a presidential campaign.

The post alluded to the "two visions for society" offered by the 2016 candidates and what led them to publicly support Clinton over 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.

The largest donations from the couple will go to the League of Conservation Voters (LCV) Victory Fund and For Our Future PAC, both of which will receive $5 million.

In a tweet, Moskovitz said he had not yet met with Hillary Clinton and insisted that despite skepticism to the contrary he's made no deals in exchange for the donations.

@hobbitj @teddyschleifer I have not yet met them, but hope to soon. We asked for nothing, but I accept that many won't believe it.

Other groups that received money are: the Hillary Victory Fund, the Democratic Senatorial Campaign Committee (DSCC), the Democratic Congressional Campaign Committee (DCCC), Color of Change PAC, For Our Future PAC, and MoveOn.org Political Action.

Silicon Valley has played a more prominent role in the 2016 campaign than in previous elections. A group of prominent tech executives from companies like Apple, Google, and Tesla -- usually a group reticent to openly discuss political issues -- joined the anti-Trump movement earlier this year.

In August, Meg Whitman, the current CEO of Hewlett Packard Enterprise, Chairwoman of Hewlett Packard and former CEO of eBay, announced her support for Hillary Clinton despite her being a prominent Republican.

And, of course, billionaire tech venture capitalist Peter Thiel has been a vocal Trump supporter, even speaking at the Republican National Convention.

CNN notes that the size of the donation will make the couple the third biggest donors of the 2016 campaign thus far.

The biggest donor has been hedge fund investor-turned-climate activist Tom Steyer, who has given over $30 million to various Democratic organizations. The second largest set of donations -- just a little over $20 million -- was made by Robert Mercer, who originally backed Ted Cruz in the GOP race but is now supporting Trump.
