President Trump on Sunday again sought to cast doubt on the existence of climate change, ridiculing Sen. Amy Klobuchar, D-Minn., for discussing global warming at her presidential campaign kickoff in a “virtual blizzard of snow.”

“Well, it happened again. Amy Klobuchar announced that she is running for President, talking proudly of fighting global warming while standing in a virtual blizzard of snow, ice and freezing temperatures. Bad timing. By the end of her speech she looked like a Snowman(woman)!” he tweeted.
