If you missed Lester Holt's interview with Donald Trump, you missed... well... not much. President Trump handled himself fairly well, Holt spent most of his time interrupting, and little or no news was made. You can tell Holt was desperate for something juicy, but If you pay attention to developing stories, there wasn't much meat on the bone. I suspect he walked away disappointed.
However boring it may have been, there are a couple of interesting tidbits - both of which occurred outside of the actual sit down.
