Bill de Blasio, the mayor of the most populated city in America, is not one to shy away from crowds and is now joining the biggest Democratic presidential field in recent history.
New York City's mayor announced his campaign launch Thursday on ABC's "Good Morning America." He joins more than 20 Democratic candidates in the race for the White House.
He's been critical of the last two presidents.
According to the Associated Press, during a trip to New Hampshire in March, he said, "[President Barack] Obama, I think, nobly went at health care, but it played out over such a long time and it got treated politically as such a narrow, instead of universal item, tragically, that it was a lost window. And I’m not saying anything I don’t think a lot of people feel."
De Blasio has also been a strong critic of President Donald Trump's. Ahead of his announcement, he held a news conference about an anti-pollution law in the lobby of Trump Tower in New York City. Trump supporters heckled de Blasio with signs and chanted as he said he was putting the president on notice.
"Your polluting buildings are part of the problem," he said.
Now de Blasio aims to be, what he believes, is part of a solution.
