President Obama is welcoming mayors from across the country to the White House today. 

At a reception for the nearly 300 attending the 82nd Winter Meeting of the U.S. Conference of Mayors, Obama reminded city leaders there's a lot more work to be done to make sure every person has a chance to get ahead. 

The President told the mayors that he will not wait on Congress to get things done to help the cities. 

He said there are plenty of people in Washington who could learn a thing or two from the people attending the conference.

Among those attending the reception was New Bedford Mayor Jon Mitchell. (Metro Networks Inc.)
