Intro

President Trump has declared that his second term will begin with the “most extraordinary first 100 days of any presidency in American history.” To track, interrogate and challenge his most consequential actions during his first few months in office, Times Opinion’s deputy editor, Patrick Healy, is beginning a weekly series on “The Opinions” focused on Trump’s first 100 days. He kicks things off with the Times writer David Wallace-Wells, exploring the president’s executive orders on climate and energy as Mr. Trump prepares to tour the destruction wrought by the recent wildfires in Los Angeles.
