New York City Mayor Bill de Blasio promised Monday to usher the city into a “new progressive era” that will spread beyond the city’s “borders.”

“Something big is happening in New York City,” de Blasio told a crowd of hundreds gathered in front of City Hall Monday. The 56-year-old Democratic mayor announced a commitment to bring about “a new progressive era in this city’s history,” one that will be “felt beyond our borders.”

De Blasio was sworn in Monday for his second and final term as the city’s mayor. Progressive stalwart Sen. Bernie Sanders of Vermont administered de Blasio the oath.

De Blasio, New York Mayor, has instituted a number of progressive policies in the name of health.

The mayor pushed a rule in 2015 that required chain restaurants in the city to post warnings for high-sodium menu items. The ruling was upheld in a New York appeals court the following year.

“New Yorkers deserve to know a whole day’s worth of sodium could be in one menu item, and too much sodium could lead to detrimental health problems,” de Blasio said in 2016.

De Blasio said his re-election with 66 percent of the vote was a “mandate” to continue pushing the progressive agenda.
