PRINCETON, N.J. (AP) – Governor Corzine, Democrat of New Jersey, will resume his duties Monday morning, just weeks after sustaining serious injuries in an auto accident that he initially feared might kill him.

Senate President Richard J. Codey had been serving as acting governor since the April 12 crash along the Garden State Parkway, in which Mr. Corzine broke his leg, 11 ribs, his collarbone and sternum. However, Tom Shea – Mr. Corzine’s chief of staff – sent Mr. Codey a letter Sunday informing him that Mr. Corzine would officially be back at work at 9 a.m.

Mr. Corzine had told The Associated Press on Saturday that he would resume the duties of his office on Monday. However, the timing of his return was not settled until Sunday, the same day Mr. Corzine taped an interview with Matt Lauer of NBC’s “Today” show, which is slated to air at 7 a.m. Monday.

The governor also scheduled a news conference for 10:30 a.m. Monday at Drumthwacket, the governor’s mansion in Princeton, where he will work from and also undergo physical therapy as part of his recuperation. Mr. Corzine said the decision to get back to work was made after he spoke Friday with doctors and lawyers, who all agreed he could resume working as governor.

“I think we’re ready to roll,” Mr. Corzine said.

Exercise equipment has been installed in the mansion’s second-floor living area, and the outdoor pool will be heated to help with Mr. Corzine’s therapy. A portable chair lift also was brought in to help him navigate steps, but Mr. Corzine is now walking up and down stairs with crutches.

The governor spent 18 days at Cooper University Hospital in Camden, much of it in intensive care, following the crash. He underwent three surgeries on his leg and needed to use a ventilator to breathe for more than a week, but he was released April 30.

At the time of the crash, Mr. Corzine’s state trooper-driven SUV was traveling at 91 mph in a 65 mph zone just north of Atlantic City. He was headed to a meeting at Drumthwacket with radio show host Don Imus and members of the Rutgers women’s basketball team to discuss racially and sexually insensitive comments Imus had made on his program.

The crash happened when the SUV was clipped by a pickup truck and slammed into a guard rail. The pickup had swerved to avoid another vehicle that was trying to get out of the way of the governor’s vehicle.

>Mr. Corzine wasn’t wearing his seat belt, as required by state law, but he voluntarily paid a $46 fine last week and has apologized to the state. He has vowed to always wear a seat belt from now on, saying his decision not to wear one in the past was “thoughtless.”

The governor also said he was not paying attention to his driver’s speed, but praised him and another state trooper for shielding him from a fire that broke out in the SUV. The flames, Mr. Corzine said, were quickly extinguished.

During Saturday’s interview, Mr. Corzine said he does not remember much about the accident, other than recalling that he was working on papers when the crash occurred, then finding himself laying in its trunk area in severe pain.

Mr. Corzine said he feared that he might die, recalling that he was in horrible pain on the medical helicopter that took him from the crash scene in Galloway to the hospital in Camden, especially when he began to suffer chest pains.

Mr. Corzine said he would not be able to do ceremonial events while he recovers at the mansion, so he will focus on policy initiatives. However, he stressed that he will have to balance work with recovering from his injuries.
