Asked whether the Senate could pass climate change and health care reform this fall, McCain said the White House still hasn't produced a bill and suggested Obama still has yet to reach out to Republicans on the issue.

"It depends on whether the administration has a proposal. That's generally the way we work, but obviously that's not been the case here," McCain said. "It also depends on whether there's a tangible desire for bipartisanship and whether the president decides to lead. I think that some of us have a legitimate desire to say, 'Well, what is your proposal?' to the president."
