Last week we linked to an interview CNBC’s Maria Bartiromo conducted with Rep. Barney Frank (D-Mass.), in which Frank lost his cool with the interviewer. This week, he did it again, this time with Bloomberg TV’s Stephanie Ruhle. It may not have been quite as dramatic as the CNBC flap, but nobody gets PO’d over derivatives quite like the Congressman from Massachusetts. Update: I forgot Frank’s June battle with Fox Business Network’s Melissa Francis. Watch it here.
