Almost two years after Anthony Weiner resigned from Congress due to a sexting scandal, he's asking the people of New York for a second chance. He officially announced his candidacy for NYC mayor overnight on Tuesday ... even though the leaked video went online hours before its intended release. 

The video focuses on Weiner's family life, showing his young daughter and wife in a home setting.

"I made some big mistakes and I know I let a lot of people down, but I've also learned some tough lessons," he said in the campaign video. "I'm running for mayor because I've been fighting for the middle class and those struggling to make it for my entire life."
