(ABC NEWS) -- Comedian Joan Rivers has been rushed to a New York City hospital in critical condition after an emergency call that she was in cardiac arrest, according to a law enforcement source.
The New York City Fire Department transported a woman matching her description to Mt. Sinai Hospital earlier this morning after receiving a call that the woman was in cardiac arrest at an Upper East Side clinic, Yorkville Endoscopy, an FDNY source said. The law enforcement source confirmed the woman was Joan Rivers.
TMZ earlier reported that Rivers was having surgery on her vocal chords at the clinic.
