New York City Mayor Bill de Blasio said his city would abide by the Paris climate accord even if President Donald Trump withdraws the U.S. from the international agreement on addressing climate change.
De Blasio, a Democrat, slammed the president's decision on Wednesday in a series of tweets.
The president announced Wednesday that he would announce his decision on the accord "within a few days."
Mayor de Blasio has been a frequent critic of Trump. Last week, Politico reported that he rejected Trump's proposed federal budget, saying the funding cuts in the budget will be harmful.
"Children will die," de Blasio said.
