Philadelphia officials have called on Pennsylvania's governor to release $45 million in promised aid so that city schools can open on time.

The state's budget secretary, however, said the funds will only be disbursed after the district has negotiated a new teachers contract with major concessions.

The state's largest district is broke and has laid off nearly 20 percent of its staff. Superintendent William Hite said he needs $50 million by Friday in order to start classes next month.

City and state lawmakers from Philadelphia held a news conference Tuesday urging Gov. Tom Corbett to release the money.

They said the district is making major reforms and has met every criteria for the funds to be released.
