Governor Tom Corbett isn't saying anything yet about the decision he faces on whether to expand Pennsylvania's Medicaid program after a U.S. Supreme Court ruling on President Barack Obama's historic health care overhaul.
 
Corbett said Thursday his administration needs more time to review the court decision before answering questions.
 
As Pennsylvania's attorney general in 2010, Corbett joined a now-unsuccessful lawsuit seeking to overturn the provision that requires most Americans to have health insurance or pay a penalty. The high court says the law's expansion of Medicaid can proceed, but only if the federal government doesn't withhold states' entire Medicaid allotment if they don't participate.
 
Corbett made it clear that he wasn’t happy with the ruling.
 

 
The Kaiser Family Foundation estimates the expansion would provide health care to another 500,000 or so Pennsylvanians at a cost of $1-billion through 2019.
