NEW YORK -- Kerry Kennedy pleaded not guilty Tuesday to impaired driving following a hit and run crash on a Westchester County highway.
Kennedy, the daughter of the late Robert F. Kennedy and ex-wife to New York Gov. Andrew Cuomo, was cited Friday morning for being under the influence of drugs, according to the New York State Police.
"A subsequent investigation found Kennedy to be operating the motor vehicle while her ability was impaired by drugs," police said in announcing the charge against her.
In a statement she read outside court, Kennedy said doctors told her a problem with her brain caused her to drive erratically and pass out behind the wheel.
"This accident was caused not by a sleeping pill but by a complex partial seizure," she said.
"I apologize to the other drivers who were on the road that day," she said before thanking her sister Rory and brother Chris for standing by her since the crash.
"911 calls reported a white vehicle operating in an erratic manner ... that collided with a tractor-trailer," a state police press release said. "The vehicle sustained damage and a flat tire."
