NEW YORK (CBSNewYork) — Anthony Weiner has officially entered the race for New York City mayor.

After weeks of speculation, the disgraced ex-congressman made the announcement in a YouTube video late Tuesday.

“I made some big mistakes and I know I let a lot of people down, but I also learned some tough lessons,” he said on the video. “I’m running for mayor because I’ve been fighting for the middle class and those struggling to make it my entire life. And I hope I get a second chance to work for you.”

The video appeared Tuesday night but then disappeared for a few hours. It was back online by 5 a.m. Wednesday.

In the video, his wife Huma Abedin, who was a top aide to Hillary Clinton when Clinton was secretary of state, is seen in a family scene with the couple’s young son.

“We love this city and no one will work harder to make it better than Anthony,” Abedin says on the video.

Weiner outlines a platform of sorts on the video, discussing the need to help the city’s middle class.

“New York City should be the middle class capital of the world and I’ve got some ideas on how to do it — 64 of them,” he says.

“It’s getting harder and harder every day. Some of the highest rents in the country went up 20 percent in the last two years alone,” he adds.

He also touts his job performance as a former congressman who fought for 9/11 funding and health care reform.

Weiner resigned in June of 2011 in the wake of a Twitter scandal after lewd pictures he sent to at least six women surfaced. That prompted numerous calls from colleagues for the embattled lawmaker to step down.

He initially denied sending a salacious photo over Twitter, saying his account had been hacked. He then modified his story, calling it a prank. He eventually confessed that the photos were of him.

In recent interviews, he said he shouldn’t have lied about the Twitter pictures, but said he did it because he wanted to keep the truth from his wife.
