Cruz said that Democrats supported the shutdown because it benefitted them politically.
"Right now the Democrats are telling you that they want another shutdown because they think it benefits them politically," he said. "So why is it hard to understand that they forced a shutdown when they think it benefits them politically?"
When asked if he would support a clean bill to increase the debt limit, Cruz said it would be "irresponsible."
"Look, of course, we should do something. We shouldn't just write a blank check," he said. "And what the president is saying is he just wants a blank credit card to keep growing and growing the debt, and I think that's irresponsible. I think it's irresponsible to our kids and grandkids to stick that debt on them because we can't live within our means."
