Former U.S. Rep. Anthony Weiner is running for New York City mayor, he announced Wednesday morning in a video posted on his campaign website

"Look, I've made some big mistakes and I know I've let a lot of people down. But I've also learned some tough lessons," Weiner said in the 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. And I hope I get a second chance to work for you."

Now that Weiner is in the race, the Democrat will undoubtedly face questions from voters and fellow candidates about the 2011 scandal that eventually led to his resignation from Congress.
