Mayor Bill de Blasio was sworn in at his second inauguration ceremony on New Year’s Day.

Sen. Bernie Sanders officially swore in Mayor de Blasio at City Hall Monday afternoon.

"In this country, in the home of Ellis Island, our job is to bring people together with love and compassion and to end the divisions and attacks that are taking place," said Sen. Sanders.

De Blasio was re-elected for a second term in November.

De Blasio touted being the safest big city in America, noting that as of midnight, New York City recorded the lowest number of homicides since 1951.

“In this hey-day of hatred, this new dawn of divisiveness, we in our city refuse to be dragged down to a place we know is beneath us,” said de Blasio.

The mayor went on to emphasize his determination to make New York the fairest big city, serving as a progressive beacon for the nation.

Public Advocate Letitia James and Comptroller Scott Stringer were also sworn in for second terms.
