On Friday, the mayor defended his decision to run when asked how he could assure skeptical New Yorkers that presidential bid would not hurt the city as several irate city residents called into "The Brian Lehrer Show" to bash his decision to run for president.

"Don't back down in the face of a bully, confront him, take him on", he said. He also predicted that de Blasio's White House dream will "never happen".

Well, only pro-crime, pro-high-tax voters will support him, according to Trump.

New York City Councilman Danny Dromm is endorsing New York City Council Speaker Corey Johnson for mayor. "Good luck, do well".

Trump's two oldest sons, Eric and Donald Jr., who run the family company, traded barbs with de Blasio on Twitter, calling the event a political stunt.

De Blasio announced his run with a YouTube video released by his campaign. "Crime has gone down in NYC five years in a row and our economy is booming". "Pre-K For All, now it's going to be 3-K For All and keeping the city safe, safest big city in America, continuing to get safer as you've seen from the most recent news and everything we're doing to create and protect affordable housing.I think it's going to intensify as we move forward".

"We're coming for you", he added. He would need to nudge out heavyweights like former Vice President Joe Biden, Sen. Kamala Harris, D-Calif.

Even after six years overseeing a city of more than 8 million people, de Blasio faces an uphill battle to stand out among the Democratic contenders, who include former U.S. Vice President Joe Biden and liberal icons like U.S. Senators Bernie Sanders of Vermont and Elizabeth Warren of MA.

De Blasio's potential candidacy has generated little enthusiasm from hometown constituents so far.

De Blasio has already visited early-voting states, including Iowa and New Hampshire.
