Christopher James Christie (born September 6, 1962) is an American politician, former federal prosecutor, and political commentator who served as the 55th Governor of New Jersey from 2010 to 2018. During his governorship, he chaired the Opioid and Drug Abuse Commission in 2017. Christie became an ABC News contributor in 2018 after leaving office. Christie was born in Newark and raised in Livingston.

Christie volunteered for President George H. W. Bush's 1992 re-election campaign in New Jersey, and became close to Bush's state director, Bill Palatucci. Following the campaign, Christie decided to run for office, and moved to Mendham Township. In 1993, Christie launched a primary challenge against the New Jersey Senate Majority Leader, John H. Dorsey. However, Christie's campaign ended after Dorsey successfully challenged the validity of Christie's petition to appear on the ballot.  In 1994, Christie was elected as a Republican to the Board of Chosen Freeholders, or legislators, for Morris County, New Jersey, after he and a running mate defeated incumbent freeholders in the party primary. Following the election, the defeated incumbents filed a defamation lawsuit against Christie based on statements made during the primary campaign. Christie had incorrectly stated that the incumbents were under "investigation" for violating certain local laws. The lawsuit was settled out of court, with Christie acknowledging that the prosecutor had actually convened an "inquiry" instead of an "investigation", and apologizing for the error, which he said was unintentional.  As freeholder, Christie required the county government to obtain three quotes from qualified firms for all contracts. He led a successful effort to bar county officials from accepting gifts from people and firms doing business with the county. He voted to raise the county's open space tax for land preservation; however, county taxes on the whole were decreased by 6.6% during his tenure. He successfully pushed for the dismissal of an architect hired to design a new jail, saying that the architect was costing taxpayers too much money. The architect then sued Christie for defamation over remarks he made about the dismissal, eventually dropping the suit without explanation.  In 1995, Christie announced a bid for a seat in the New Jersey General Assembly; he and attorney Rick Merkt ran as a ticket against incumbent Assemblyman Anthony Bucco and attorney Michael Patrick Carroll in the Republican primary. Christie ran as a pro-choice candidate and supporter of the ban on assault weapons. Bucco and Carroll, the establishment candidates, defeated the up-and-comers by a wide margin. After this loss, Christie's bid for re-nomination to the freeholder board was unlikely, as unhappy Republicans recruited John J. Murphy to run against Christie in 1997. Murphy defeated Christie in the primary. Murphy, who had falsely accused Christie of having the county pay his legal bills in the architect's lawsuit, was sued by Christie after the election. They settled out of court with the Freeholders admitting wrongdoing and apologizing. Christie's career in Morris County politics was over by 1998.Answer this question using a quote from the following article:
