City comptroller John Liu officially launched his campaign for mayor Sunday.
Liu made the announcement surrounded by supporters on the steps of City Hall Sunday afternoon.
He joins a crowded democratic field that includes City Council Speaker Christine Quinn, Public Advocate Bill de Blasio, and former City Comptroller Bill Thompson.
In accepting the nomination for mayor, Liu said he will work to help New Yorkers who are struggling to get by.
"I, as a proud product of New York City public schools, a proud immigrant, someone who left the private sector for public service, I proudly announce that I'm running to be mayor of the city of New York," Liu said. "Because this city makes a promise with us, that every single New Yorker has the opportunity to succeed. And I'm going to make damn sure that that promise is fulfilled."
Liu is already the first person of Asian descent to be elected to citywide office, but does face questions about his fundraising.
Two former aides have been indicted in a conspiracy case and are set to go on trial next month.
