As the next showdown over raising the debt ceiling approaches, one of the Senate's leading conservatives is suggesting Republicans won't risk shutting down the government.

Appealing on "Fox News Sunday," Sen. Mike Lee (R-Utah) said Republicans will insist that Obamacare is defunded. But he said the government will be funded one way or another.

"We all know that the government's going to get funded," Lee said. "The question is whether the government gets funded with Obamacare or without it."
