Disney CEO Bob Iger says he has resigned from a presidential council following Donald Trump’s announcement on Thursday that the U.S. is backing out of the Paris Climate Accord.

Iger, who was a member of Trump’s Business Advisory Council, tweeted, “As a matter of principle, I’ve resigned from the President’s Council over the #ParisAgreement withdrawal.”

This comes hours after Tesla CEO Elon Musk had similarly tweeted that he was leaving his roles on Trump’s economic advisory board and manufacturing jobs initiative council due to the Paris Accord decision.

The Paris agreement took effect in November, with the 195 signatories focusing efforts to reduce carbon emissions by 2020.

Former president Barack Obama, who reached the deal, said in a statement on Thursday that the “nations that remain in the Paris Agreement will be the nations that reap the benefits in job and industries created.”

Obama continued, “I believe the United States of America should be at the front of the pack. But even in the absence of American leadership; even as this Administration joins a small handful of nations that reject the future; I’m confident that our states, cities and businesses will step up and do even more to lead the way, and help protect for future generations the one planet we got.”

Numerous political figures and Hollywood notables have criticized Trump’s decision, including Al Gore, Bernie Sanders, Leonardo DiCaprio, Chelsea Handler and Bette Midler.
