New York mayor de Blasio ends presidential bid

New York Mayor Bill de Blasio announced Friday that he was ending his floundering bid to be nominated as the Democratic candidate in next year's US presidential election.

"It's clearly not my time, I am going to end my presidential campaign," he said in an interview on the MSNBC television network.

De Blasio vowed to "continue my work as mayor of New York City, and I'm going to keep speaking up for working people."

"After several months of campaigning, I have reached a point where I feel I have contributed all I can to this primary," he said in an email to supporters.
