Sen. Jon Kyl explained Sunday why Sen. Jim Bunning was justified in blocking an extension of unemployment benefits. "All Senator Bunning was saying quite correctly it ought to be paid for," Kyl told Fox News' Chris Wallace.

"Congress passed the so-called pay-go legislation which is supposed to require we find offset or other savings if we are going to spend money. So the first thing we do, we exempt this bill from it," he complained.

But Kyl does believe the extension of benefits will eventually pass because they are temporary. "It will be pass, though, because it's temporary extension. The question for the longer term extension is a different issue because that's well over $100 billion," said Kyl.
