Thanks for providing links Fat. Here is Walker's comment in context.

The George W. Bush administration "arguably was the least fiscally responsible in history," Walker says, based on the swing in the federal budget from a $230 billion surplus in 2000 to a $1.2 trillion deficit in 2008.

"But the jury is out on the current administration," he says. "The numbers are shocking. Ultimately [Obama's] responsible now. He's got to come to grips with 'what are we going to do?' on his watch. We'll have to see what ends up happening."
