President Trump believes that climate is changing and that pollution is playing a part in it, according to United Nations Ambassador Nikki Haley.

Haley’s comments in a sneak peak of an interview to be aired during Sunday’s “State of the Union” on CNN come a few days after President Trump announced that the U.S. will exit the Paris climate accord which seeks to reduce global greenhouse gas emissions. That move sparked questions over whether Trump believes in climate change as several top administration officials declined to say if Trump believes in it.
