Whoa. We’re used to seeing CNBC reporter Rick Santelli rant. He established it as part his brand at the start of the financial crisis, in a tirade against the bailout that called for a new “tea party” protest. But today he cut loose on the Federal Reserve, and CNBC economics reporter Steve Liesman seems to have lost all patience with him: “There is no single piece of advice you’ve given that’s worked, Rick. Not a single one.” Watch it here. It gets heated about 2:30 in, boils over at around 6 minutes, and Santelli walks off camera at about 11 minutes.
