Comedian Joan Rivers rested comfortably on Friday at a New York hospital where she was admitted after she suffered cardiac arrest and stopped breathing during a vocal cord procedure, a spokeswoman said. There was no change in her condition from late on Thursday, when daughter Melissa Rivers issued a statement saying her 81-year-old mother was resting comfortably, said Mount Sinai Hospital spokeswoman Lucia Lee. The brash comedian and fashion critic had gone to a New York clinic for a vocal cord procedure on Thursday. Without identifying Rivers specifically, the Fire Department of New York said a patient reported to be in cardiac arrest was taken to Mount Sinai from Yorkville Endoscopy by emergency workers at mid-morning.
