Gov. Arnold Schwarzenegger (R-Calif.) backed off his support for Democratic healthcare reform today, saying he's "concerned" about recent changes to the legislation.

"As a governor, I'm right now concerned with where they are," Schwarzenegger told ABC's Good Morning America. "As a matter of fact, I, you know, I'm not supporting it as much anymore with this enthusiasm because the fact is is that now it will cost our state $3 billion if they pass this health care bill."

Schwarzenegger had previously endorsed President Obama's plans for reform. But he suggested this morning that Democrats have been too eager to cut a deal.

"The important thing is that we need health care reform," he said. "But I think it is also important to do it the right way, and not just to make the deal itself become the main point and not the substance of the deal."
