Which of the President's decisions will have the most significant long-term effect? (Michael Grunwald)

President Trump is constantly making headlines about the latest Obama-era program he’s eliminating, the international agreements he is doing away with or whichever historical norms he’s choosing to ignore on a given day. But what is the action in this constant flurry of activity that he will be best remembered for? On this week’s TrumpWatch, Jesse looks at which of the President’s actions will be the most transformative with Michael Grunwald, senior staff writer for Politico Magazine and the author of the article “Donald Trump Is a Consequential President. Just Not in the Ways You Think.” He’s also the creator of the publication’s Did-It-Matter-Meter, assessing both the immediate and far-reaching consequences of the President's actions.
