WASHINGTON — After a series of attacks against immigrants and minorities since Election Day, the financier George Soros says he will commit $10 million from his personal foundation to combat a rise in hate crimes that he linked to the “incendiary rhetoric” of President-elect Donald J. Trump’s campaign.

Mr. Soros, a Holocaust survivor originally from Hungary, said in a telephone interview this week that he was “deeply troubled” by hundreds of reports of possible hate crimes since the election — including many Nazi swastikas spray-painted on cars and buildings.

“We must do something to push back against what’s happening here,” Mr. Soros said, blaming what he termed the “dark forces that have been awakened” by the election.

Groups that oppose Mr. Trump’s policies have reported record donations since the election, among them the American Civil Liberties Union, the Sierra Club and Planned Parenthood.
