Out of the running: De Blasio dropped out of the race on Sept. 20 after failing to gain traction in a crowded primary field. The New York City mayor struggled in the polls and did not qualify for the third round of Democratic primary debates, hosted by ABC News. He had only received 6,700 unique donations in the second fundraising quarter.
"Getting out there, being able to hear people's concerns, address them with new ideas has been an extraordinary experience," he said on MSNBC. "But I have to tell you, at the same time I feel like I've contributed all I can to this primary election and it's clearly not my time. So I'm gonna end my presidential campaign, continue my work as mayor of New York City and I'm gonna keep speaking up for working people."
While he did not endorse another candidate, de Blasio said he'll support whomever secures the Democratic nomination.

What he used to do: De Blasio served as Housing and Urban Development regional director, as a Brooklyn School District school board member and as a New York City councilman for the 39th district. He also headed Hillary Clinton's successful 2000 U.S. Senate bid. De Blasio started his public service career in 1989 working on New York City Mayor David Dinkins' campaign.
Key life/career moments:
He's perhaps most notably known for implementing universal pre-kindergarten in New York City.
Crime rates are also at record lows, though critics have questioned if crime is going unreported.
Where he stands on some of the issues:
De Blasio has staked his campaign on issues that most directly affect working families. Chief among them: income inequality.
"The real issue in this country is that working people are stuck economically," he said to ABC News Chief Anchor George Stephanopoulos on "This Week."
De Blasio said he believes everyone should have a right to health care.
"Let's face it, the emergency room is the family doctor now for millions and millions of Americans," de Blasio said. "And tax dollars pay for it. It is expensive, it's backwards and it means people get really, really sick before they ever seek help."
That's why de Blasio said he unveiled a new health care program in New York City that would guarantee health care to all city residents, regardless of their ability to pay or immigration status.
"If they get sick, everyone gets sick. If the whole community isn't healthy, then we all suffer," de Blasio said of including about 300,000 undocumented New Yorkers. "That's the blunt reality of this country -- undocumented immigrants are part of our economy."
According to his campaign, de Blasio raised about $1 million during the second quarter of 2019, finishing with $728,000 on hand. Over 90 percent of the contributions -- from 6,700 total donors -- were $50 or less, the campaign said.
De Blasio entered the race six weeks before the close of the second quarter. The campaign said $630,000 was raised in the wake of the first Democratic presidential debates in June.

De Blasio, a graduate of NYU and Columbia University, was elected New York City mayor twice in landslide victories.
His wife, Chirlane, is a poet and activist. They met while working in Dinkins' administration, according to a piece she wrote on Refinery29. They have two kids: Chiara and Dante.
In his 20s, he changed his last name to his mother's, saying that she had been the most important influence in his life.
