Gina Cherwaty of Selbyville is suing the government over injuries she says she sustained in 2016 when Secret Service agent James Hall ran a red light in Wilmington and struck several cars, including hers. In a court filing Wednesday, government lawyers denied any negligence by Hall, while not specifically addressing whether he ran a red light. Secret Service deputy director William Callahan wrote in February that Hall's vehicle was operating its emergency lights and siren and had slowed to a near stop. Cherwaty's lawyer rejected that argument, saying a vehicle in a motorcade is not an authorized emergency vehicle, and that witnesses reported no lights or siren.
