Facebook co-founder Dustin Moskovitz — a newcomer to politics as of last month — will donate $15 million more, including $5 million to the largest super PAC supporting Hillary Clinton, Priorities USA Action, in the wake of the latest news about Donald Trump.

"The events of the past few weeks have only deepened my conviction that Hillary is the best choice for America," Moskovitz said Saturday in a Medium post. "I hope that these contributions will help make that outcome a reality."


Moskovitz said $8 million of his new donation money will go to political groups, with $5 million headed to Priorities, and $7 million to nonpartisan groups dedicated to voter registration and get-out-the-vote efforts.

In early September, he waded into politics for the first time with a series of donations adding up to $20 million. His combined contributions make him one of the single largest donors of the cycle.
