The former Wall Street executive and US ambassador to Germany will become the state's 56th governor after he is sworn in at the War Memorial in Trenton.
Among the dignitaries sitting on stage behind him were his wife, Tammy, and their four children, Josh, Emma, Charlie, and Sam; Christie and his wife, Mary Pat; Senate President Steve Sweeney; Assembly Speaker Craig Coughlin; U.S. Sen.
Murphy put his hand on the same bible that President John F. Kennedy - his political hero and fellow MA native - used to be sworn in 57 years ago. In particular, his calls to make the state's tax code fairer, raise wages for low-paid New Jerseyans, protect our state's striving immigrants, rein in overzealous tax breaks for corporations and allow all New Jersey workers to access earned sick time are all welcomed, and we look forward to working with his administration and the new Legislature to move these ideas from words in a speech to strong policies improving the lives of millions of New Jerseyans.
A former Democratic Obama administration diplomat is taking over the New Jersey governor's office from Republican Chris Christie on Tuesday.
Murphy also took aim once again at President Donald Trump, a Republican he has widely criticized and vowed to combat.
The new governor earned his fortune, which he used to help win the Democratic nomination past year, as an executive at Goldman Sachs. Christie leaves office on Tuesday after two terms as governor.
Murphy also thanked former Christie for his service and praised his work on the opioid crisis, the AP reported.
"The long-term common good, along with our confidence and optimism about what we can achieve, has suffered", Murphy said.
Minutes later, Murphy - who beat Republican Kim Guadagno, the outgoing lieutenant governor, in November's election to win the job - outlined how he would roll back many of Christie's policy decisions, from defunding women's clinics to backing off climate change efforts.
Murphy's inaugural address was unabashedly liberal, calling for the wealthy to pay higher taxes, more funding for Planned Parenthood and a $15 minimum wage.
"And, I promise you now that they will be met with a signing ceremony instead of a veto pen", he added - a reference to Christie many vetoes and his record of defeating veto override attempts. Clinics later closed and cut their hours.
