Keeping a key campaign promise, President Trump announced his intention to withdraw from the Paris climate agreement in a Rose Garden speech this afternoon, trumpeting an "America first" message that the United States will forge its own path on climate change — joining Nicaragua and Syria as the only nations outside of the agreement.
Trump's big line: "I was elected to represent the citizens of Pittsburgh — not Paris."
The key quote: "As of today, the United States will cease all implementation of the non-binding Paris accord and the draconian financial and economic burdens the agreement imposes upon our country."
The mechanism: The U.S. is expected to exit the Paris deal via the formal withdrawal procedures included in the agreement, a process that could take three to four years to complete. The administration chose not to exit the underlying U.N. climate change treaty — which would have been a faster but much more tumultuous choice.
