George Soros, a billionaire philanthropist and long-time supporter of progressive causes, spoke at the World Economic Forum on Thursday.

And he didn’t have many nice things to say about President Donald Trump.

According to the Associated Press, Soros told an audience of world leaders and business magnates that Trump is a “con-man,” a “climate denier, and the “ultimate narcissist.”

While he also said that Trump is a “dictator,” he levied the same criticisms against Chinese President Xi Jinping and Prime Minister Viktor Orban of Hungary, deeming them tyrannical autocrats.

After the speech, he told reporters waiting in the lobby that he would be pledging over $1 billion to his new education program — Open Society University Network.

“To demonstrate our commitment to OSUN, we are contributing $1 billion to it,” he said. “But we can’t build a global network on our own; we will need partner institutions and supporters from all around the world to join us in this enterprise.”

Soros stated that OSUN is the “most important and most enduring project of my life,” adding “And I would like to see it realized while I am still around.”

The billionaire has made his fortune through the markets and has spent much of his time advocating for progressive ideas and institutions. He began the Open Society Foundation in 1993, which provides funds for social justice organizations around the world that look to advance “justice, education, public health and independent media.”

Since it opened, over $15 billion have been donated to various groups.
