Rachel Maddow ran about a minute of it, and then Lawrence O'Donnell had another couple minutes. You likely thought that that was the bulk of the speech, especially during the O'Donnell show Sen. Bennet commented, "One final point." In fact, he was just getting warmed up. Those two segments were during the first four minutes of his comments. His "one final point" went on for another...20 minutes! It was a "One more thing..." moment that would make Columbo proud.
I will only single out one brief moment from it, since it didn't get covered in the excerpts I saw, and it's a critical point that bears repeating endlessly. I won't write it with the outraged fury he says it, but feel free to read it that way -- that this is a wall no one in this room wants, that the American public doesn't want, and that even Trump knew it was a promise with Mexico paying for it that he could never keep -- and we've shut the government down over it!!!
Here's the whole thing. Do check it out for another, oh, five minutes after what MSNBC showed. Make it to the nine-minute mark. I have a feeling you'll keep watching beyond that.
