Sen. Bernie Sanders stood up from his chair and tried to end an interview with ABC News when he was asked Sunday whether he would like Rep. Alexandria Ocasio-Cortez to join him in the U.S. Senate. "Right now, we have, as I said, just a whole lot of people in the Congress. OK, Jonathan, thanks," Sanders, I-Vt., told ABC News' Jonathan Karl, as he got out of his seat, in response to a question about Ocasio-Cortez potentially running for the Senate. "You want to do nonsense, do nonsense," Sanders added. "I don't want to talk about inside the Beltway stuff." Ocasio-Cortez's future has been the subject of intense speculation as she and Sanders, two political rock stars among progressives, have been drawing massive crowds as they hold a series of rallies in swing districts. More than 30,000 people attended a "Fighting Oligarchy" rally in Denver on Saturday held by the 83-year-old Sanders and 35-year-old Ocasio-Cortez.
