Answer by taking a quote from the following article:

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. In March 2010, Christie signed into law three state pension reform bills, which had passed with bipartisan support. The laws decreased pension benefits for future hires and required public employees to contribute 1.5 percent of their salaries toward their health care. The laws prompted a lawsuit by the police and firefighters' unions. In his campaign for governor, Christie opposed any change in pension benefits for firefighters and law enforcement officers, including "current officers, future officers or retirees". He described the pension agreement as "a sacred trust". Later that year, he called for further cuts, including the elimination of cost-of-living adjustments for all current and future retirees. In June 2011, Christie announced a deal with the Democratic leadership of the legislature on a reform of public employee pensions and benefits. The deal raised public employees' pension contributions, mandated the state to make annual payments into the system, increased public employee contributions toward health insurance premiums, and ended collective bargaining for health benefits. The reform is projected to save the state $120 billion over 30 years. In June 2013, Christie signed a $33 billion state budget that makes a record $1.7 billion payment to the state's pension fund and also increases school funding by almost $100 million. The budget resulted from negotiations between Christie and Democratic leaders in the state legislature and was the first that Christie has signed as passed, without vetoing any of its provisions. In May 2014, Christie cut the contributions to New Jersey public workers' pension funds for a 14-month period by nearly $2.5 billion to deal with a revenue shortfall in the state budget of $2.75 billion. The state will instead make a $1.3 billion payment during the period. Christie cited the state constitution's requirement to have a balanced budget for his decision to cut payments to pensions for state workers, and follows Christie's changes to the state's pension formula earlier in 2014 to save $900 million through the end of his term. Christie has stated that he believes that the New Jersey Department of Environmental Protection is too big and is "killing business" with permit delays and indiscriminate fines. He announced that, if elected, the agency would be his first target for government reduction: he would reduce its workforce and strip it of its fish and wildlife oversight. Christie has stated that he intends to simultaneously spur growth in the state's manufacturing sector and increase New Jersey's capability to produce alternative energy. He has proposed a list of policy measures to achieve this, including giving tax credits to businesses that build new wind energy and manufacturing facilities, changing land use rules to allow solar energy on permanently preserved farmland, installing solar farms on closed landfills, setting up a consolidated energy promotion program, and following a five-to-one production to non-production job ratio in the creation of new energy jobs. In August 2010, legislation to encourage the development of wind power in New Jersey was signed by Christie at the Port of Paulsboro. The Offshore Wind Economic Development Act authorized New Jersey Economic Development Authority to provide up to $100 million in tax credits for wind energy facilities. The governor has pledged to ban coal-fired power plants, and to reach 22.5% renewable generation in the state by 2021. On May 26, 2011, Christie announced he would pull the state out of Regional Greenhouse Gas Initiative. This was challenged in court which ruled in March 2014 that Christie had acted illegally in doing so since state regulations do not permit it. His administration is seeking to repeal the rules.
