New York Mayor Bill de Blasio has announced his run for the presidency, the latest Democrat to enter the race.
In a video released on Thursday, Mr de Blasio said it was “time we put working people first” and said President Donald Trump “must be stopped”.
“I’m a New Yorker, I’ve known Trump’s a bully for a long time,” he added. “I know how to take him on.”
He is expected to visit Iowa and South Carolina to begin campaigning this weekend.
Mr de Blasio is the latest of more than 20 people to officially declare their candidacy to become the Democrat’s presidential nominee and challenge President Trump in 2020.
