Former Secretary of State John Kerry on Friday said the Paris Agreement will continue without the United States, but believes the country will remain committed to the climate deal.

Kerry, who signed the climate agreement in 2016, slammed President Trump’s decision to pull out of the agreement on Thursday. “For the president of the United States, when he didn’t need to, to unilaterally walk away from the agreement, he’s aligned us with Syria and Nicaragua. By the way, Nicaragua wanted to do more. So, we’re last not first,” he said in an interview with NPR on Friday.
