But if his efforts, could shutdown the federal government.
In the three years after being signed into law, Republicans have tried to repeal ObamaCare more than three dozen times.
“This will probably be the last opportunity we'll have to not fund ObamaCare before these provisions are scheduled to take effect on January 1, 2014,” Sen. Lee told ABC 4 Utah’s Kim Johnson. “So in that respect, it's the end of the road.”
Lee is part of a group of senate Republicans proposing to block any government funding resolution that includes money for ObamaCare. This fall, Congress is expected to vote on a continuing resolution that essentially keeps the federal government running when congress fails to pass a budget.
“I and a group of senators have indicated that we will not vote for any continuing resolution that includes ObamaCare funding,” said Sen. Lee.
Lee said the intention is not to shutdown government, but to get Democrats to remove ObamaCare funding from the CR.
“We don’t want a shutdown, we don't need a shutdown, we're certainly not proposing a shutdown nor do we anticipate that Harry Reid would go so far as to shutdown the government just to defend a law that the president himself has acknowledged is not ready to be implemented,” he said.
If Lee is successful only parts of ObamaCare that haven't taken affect, such as the individual mandate, would be in jeopardy.
But even though the U.S. Supreme Court upheld the individual mandate and democrats say the law as a whole will lower insurance costs, Sen. Lee insists the law is bad for the country and is hoping other congressional republicans will join him in perhaps a final effort to stop it.
“We have some leverage here, let's use that and let's get this done,” he said.
Lee said support for his plan is growing. Right now 15 senators have signed on, but more than 40 will be needed to block the continuing resolution.
