While Onorato picks up support from Pittsburgh's congressman, Anthony Williams gets one of Philadelphia's, Bob Brady. From the Daily News:

State Sen. Anthony Hardy Williams declared the May 18 Democratic primary election a race between himself and Allegheny County Executive Dan Onorato this morning while accepting the endorsement of U.S. Rep. Bob Brady, his party's chairman in Philadelphia. Williams also clearly chafed at suggestions that he is a one-issue candidate because most of his $1.5 million political war chest comes from a handful of people interested in education reforms such as using public money to pay for private school tuition.
