NEW YORK - Anthony Weiner is officially making a run for the New York City mayor's office.

The former Brooklyn congressman made the announcement in a video posted to his YouTube account overnight. It features him with his family in the city, taking viewers on a ride to where it all began at his childhood home in Park Slope and his elementary school, P.S. 39.

Weiner resigned from his post two years ago amid a sexting scandal that involved tweeting raunchy photos of himself. He briefly mentions his indiscretions during the video, saying in part, "I made some big mistakes and I know I let a lot of people down, but I also learned some tough lessons."

In a recent poll, Weiner came in second behind City Council Speaker Christine Quinn in the mayoral race. The Democratic Primary is in September.
