Fresh off a come-from-behind victory in keeping the Kings NBA franchise in Sacramento, Mayor Kevin Johnson gets another chance to build his reputation as a political heavyweight. He will be introduced Wednesday, April 16, 2014, as the newest president of the U.S. Conference of Mayors, giving the former NBA All-Star a chance to promote California's capital and the interests of local governments across the country.
