Facebook co-founder Dustin Moskovitz and his wife Cari Tuna have pledged $20 million for presidential elections for the first time against Republican presidential candidate Donald Trump.

The 32-year-old billionaire and his wife have pledged support to the Hillary Victory Fund, the Democratic Senatorial Campaign Committee (DSCC), the Democratic Congressional Campaign Committee (DCCC), the League of Conservation Voters (LCV) Victory Fund, For Our Future PAC, MoveOn.org Political Action, Color Of Change PAC and several nonpartisan voter registration and Get out the vote (GOTV) efforts.

Moskovitz made the announcement on a blog called Compelled to Act, in which he condemned the polarisation in America due to Trump. He called on fellow citizens to "choose to aim resolutely down the second path" of "increased tolerance, diversity and interdependence in the name of mutual prosperity."

"In this version of society, we all work together to create a thriving worldwide community," Moskovitz wrote.

The entrepreneur attacked Trump directly when he said, "If Donald Trump wins, the country will fall backward, and become more isolated from the global community. This distinction is starkly caricatured by his #1 'policy' position: the literal building of a wall between us and our neighbour."

He supports Clinton for her "vision of optimism, pragmatism, inclusiveness and mutual benefit."

The husband and wife, the techpreneur wrote, are donating for a presidential campaign for the first time and they hope that it helps Secretary Clinton win.

"This decision was not easy, particularly because we have reservations about anyone using large amounts of money to influence elections," he added.

Anticipating criticism for pledging such a huge amount, he said that there might be theories.

"Those who know us best will see the sincerity of our intentions, and can attest that the thoughts above represent the full scope of our motivations," he said.
