New York City Mayor Bill de Blasio will declare his bid for the presidency on Thursday, a campaign spokesperson said on Wednesday, joining the almost two dozen other candidates already competing for the Democratic nomination.

De Blasio will make the formal announcement Thursday morning and then travel to Iowa and South Carolina for multiple stops over four days. His wife, Chirlane McCray, who has been a highly visible presence and close adviser during his six years at City Hall, will join him for part of the trip.

The mayor plans to highlight his record of liberal accomplishments in the nation’s largest city, including enacting universal pre-kindergarten, raising the minimum wage to $15 an hour, and overseeing a drop in crime to an all-time low.
