President Trump has privately told multiple people, including EPA Administrator Scott Pruitt, that he plans to leave the Paris agreement on climate change, according to three sources with direct knowledge.

Publicly, Trump’s position is that he has not made up his mind and when we asked the White House about these private comments, Director of Strategic Communications Hope Hicks said, “I think his tweet was clear. He will make a decision this week.”

Why this matters: Pulling out of Paris is the biggest thing Trump could to do unravel Obama’s climate policies. It also sends a stark and combative signal to the rest of the world that working with other nations on climate change isn’t a priority to the Trump administration. And pulling out threatens to unravel the ambition of the entire deal, given how integral former President Obama was in making it come together in the first place.
