A former New Jersey environmental official says the office of Gov. Chris Christie pushed through a favorable settlement that potentially saved the oil giant ExxonMobil billions of dollars. New Jersey quietly agreed to accept just $250 million from Exxon after initially seeking $8.9 billion for environmental contamination more than a decade ago. The settlement came just two months after the state attorney general’s office made a strong demand for the original $8.9 billion claim. Writing today in The New York Times, Bradley Campbell, the former commissioner of New Jersey’s Department of Environmental Protection, says Governor Christie’s chief counsel, Christopher Porrino, “inserted himself into the case, elbowed aside the attorney general and career employees who had developed and prosecuted the litigation, and cut the deal favorable to Exxon.” [Have to wait for decade to get justice. But that also favorable to company]
