WASHINGTON, May 16 (Xinhua) -- New York City Mayor Bill de Blasio announced Thursday that he's seeking the 2020 Democratic nomination for U.S. president.
De Blasio is the 23rd Democrat joining the crowded race, where he will compete with rivals such as former Vice President Joe Biden and Senator Bernie Sanders of Vermont.
"Today I am proud to announce my candidacy for president of the United States of America, because it's time to finally put working people first," the mayor said on Twitter.
De Blasio, 58, was first elected Mayor of New York City, the nation's largest city, in 2013 and retained his office in 2017.
A critic of the White House's immigration policy, De Blasio has also championed the fight against climate change.
U.S. President Donald Trump slammed De Blasio Thursday morning.
"He is a JOKE, but if you like high taxes & crime, he's your man," Trump wrote in a tweet. "NYC HATES HIM!"
