How much credit does Donald Trump deserve for job creation since election?

President-elect Donald Trump has proudly taken to Twitter after GM and Carrier announced domestic investments, but how much credit does he deserve for their actions? MSNBC’s chief legal correspondent, Ari Melber, tells TODAY that Trump’s impact on job creation or preservation is “very small or non-existent" according to companies he’s heard from. Melber notes that companies’ hiring decisions are “months if not years in the making. They are not responses to a couple of days of internet attention.”
