President Donald Trump uttered nearly 3,000 words Thursday explaining why he withdrew the United States from the Paris climate accord. But he never spoke the two words the global agreement was designed to combat: climate change.

While candidate Trump dubbed climate change a “hoax” and “bulls—,” senior White House officials are mum about whether President Trump still thinks that. On Friday morning, senior White House aides, including counselor Kellyanne Conway, declined to answer questions about the president’s personal beliefs on climate change during television interviews.

Under a warm late-spring sun Thursday in the White House Rose Garden, Trump cast his decision to leave the global agreement as one about protecting U.S. workers and bolstering national pride — joining Nicaragua and Syria as the only countries not participating.

“The Paris climate accord is simply the latest example of Washington entering into an agreement that disadvantages the United States to the exclusive benefit of other countries, leaving American workers — who I love — and taxpayers to absorb the cost in terms of lost jobs, lower wages, shuttered factories, and vastly diminished economic production,” Trump said in what conservatives dubbed one of his best speeches since taking office.
