The ‘crooked’ charge against NBC: Why the Donald Trump-Kristen Welker slugfest went off the rails

The headlines say Donald Trump "stormed" out of his interview with NBC’s Kristen Welker.

The reality was a little more subtle.

It’s easy to second-guess. The natural tension that comes with interviewing any politician for television – but especially this president, who can dominate this kind of sit-down – calls for split-second judgments.

Having interviewed Trump numerous times – especially in a high-stakes session two weeks before the election, at his invitation – gives me a certain perspective.
