Sen. Ted Cruz, R-Texas, surprised ABC's Jonathan Karl on "This Week" on Sunday after he refused to take responsibility for the government shutdown in October.

The way Cruz sees it, the fault lies with Senate Majority Leader Harry Reid, D-Nev., and President Obama.

“I think it was absolutely a mistake for President Obama and Harry Reid to force a government shutdown,” he replied, after Karl asked him if he would admit that the tactic was a mistake.

"But I mean, but c'mon, we're a couple of months away from this." Karl responded in disbelief. "The only reason this happened because you insisted -- Republicans insisted -- that Obamacare be defunded as a condition of funding the government. If you took that away that insistence, there would be no shutdown. I mean really."
