the board of trustees. Corzine also nominated Oliver Quinn, Prudential Financial's vice president and chief ethics officer, as vice chairman of the board. Corzine's commissioner of the Department of Environmental Protection and Chief of Staff, Lisa P. Jackson was nominated as the administrator of the United States Environmental Protection Agency. She was confirmed by the Senate on January 22, 2009. Motorcade accident On April 12, 2007, Corzine and 25-year-old aide Samantha Gordon were injured in an automobile accident on the Garden State Parkway near Galloway Township while traveling from the New Jersey Conference of Mayors in Atlantic City to Drumthwacket, his residence in Princeton, to meet with radio personality Don Imus and the Rutgers University women's basketball team. The New Jersey State Police determined that Corzine's SUV, driven by a state trooper, was traveling in excess of with its emergency lights flashing when the collision occurred. A pickup truck drifted onto the shoulder and swerved back onto the lane, and another pickup truck swerved to avoid the truck and hit the Governor's SUV, causing the SUV to hit the guardrail. The State Police reviewed roadside camera recordings and E-ZPass records to track down the driver of the truck; he was not charged with any violation. Corzine and the trooper were flown by helicopter to Cooper University Hospital in Camden, a Level I trauma center. The aide was taken by ambulance to Atlantic City Medical Center. Neither the NJ State Trooper nor the aide was seriously injured, but Corzine suffered broken bones, including an open fracture of the left femur, 11 broken ribs, a broken sternum, a broken collarbone, a fractured lower vertebra, and a facial cut that required plastic surgery. The Governor was not wearing a seat belt. Friends had long said that they had rarely seen him wear one. When asked why the state trooper who was driving would not have asked Corzine to put on his seat belt, a staffer said the governor was "not always amenable to suggestion". The Superintendent of State Police has also noted that the trooper could be charged if the crash were preventable. By April 23, 2007, Corzine's doctors had upgraded him from critical to stable condition. He was sedated and unable to speak because of a breathing tube in his throat, and as such, was unable to perform his duties as governor.
