State Rep. Sandy Pasch, D-Whitefish Bay, accused Walker of playing politics "with the health of our communities,"

"This brazen attempt to score short-sighted political points with extreme partisan interests by playing chicken with federal law will take Wisconsin's health care decisions out of our hands and give them to the federal government. It is penny-wise, pound-foolish, and most certainly presents a missed opportunity for Wisconsin to control its own destiny in designing a quality, consumer-friendly exchange," Pasch said in a statement.
