Dustin Moskovitz, one of the co-founders of Facebook, pledged $20 million to assist Democrats in stopping the Republican presidential candidate Donald Trump from winning the upcoming presidential elections, according to CNN reports. This pledge by Moskovitz will be the the third largest sum of monies given to a campaign on record.

Moskovitz said the following as he made his pledge:

“This decision was not easy, particularly because we have reservations about anyone using large amounts of money to influence elections. We hope these efforts make it a little more likely that Secretary Clinton is able to pursue the agenda she’s outlined, and serve as a signal to the Republican Party that by running this kind of campaign — one built on fear and hostility — and supporting this kind of candidate, they compel people to act in response.”
