Anthony Weiner's run for a renaissance is officially on.

The ex-congressman who resigned over raunchy tweets that he's in the New York City mayoral race. He had said last month he was considering it.

The video was posted  to a campaign YouTube page and then taken down although it reappeared around 5 a.m. on Wednesday morning on his campaign website.

In the video Weiner says, “Look, I made some big mistakes, and I know I let a lot of people down,'’ he says. “But I’ve also learned some tough lessons," reports the New York Times. Weiner comes to the rescue of the middle class in his video, claiming “The very people that put everything they had into this city are getting priced right out of it,'’ he says. “But it doesn’t have to be that way.”

The video focus' on Weiner and his family, showing scenes of he and his wife Huma Abedin feeding their infant son Jordan. At the end of the video they are seen sitting together and she says, "We love this city, and no one will work harder to make it better than Anthony," according to the Times.

Weiner is expected to make a formal announcement on Wednesday.

The Democrat is jumping into a crowded field for September's primary. He's arriving with some significant advantages, including a $4.8 million campaign war chest, polls showing him ahead of all but one other Democrat — and no end of name recognition.

But he also continues to contend with questions about his character and the scandal that sank his career just two years ago.

After a photo of a man's underwear-clad groin appeared on his Twitter account, he initially claimed his account had been hacked. He eventually owned up to exchanging racy messages with several women.
