Sen. Mike Lee (R-Utah), one of the leaders of the Defund Obamacare effort, assured Sunday that the effort will not lead to a government shutdown.

Asked point-blank about a potential shutdown, Lee said -- as he has said before -- that it won't come to that.

"No. We all know that the government is going to be funded. The questions is whether it will be funded with Obamacare or without," Lee said on NBC's "Meet the Press."
