Sen. Ted Cruz, R-Texas, along with 17 other Senate Republicans, has introduced a bill to fully defund Obamacare in the wake of the recent string of bad news surrounding the law.

"The Administration's recent announcement to delay the onerous and unpopular employer mandate until after the 2014 election, coupled with its announcement to delay income and health status eligibility requirements in favor of an honor system for the most expensive entitlement for our generation, confirms what has been obvious from the start--this law is a colossal mistake," Cruz said in a press release.

The Defund Obamacare Act of 2013 would deauthorize all future appropriations for the bill and rescind all prior appropriations that were used to fund Obamacare.

Cruz is joined by Rep. Tom Graves, R-Ga., who introduced companion legislation in the House. Graves has introduced similar legislation before, in March of 2013, and also in the 111th and 112th congresses.

"We must seize the moment and permanently delay the entire law," Graves wrote in his own press release. "Congress can do this. We control the purse strings and can protect taxpayers from funding Obamacare. Businesses have their delay and the special interests have their waivers. Let's not leave working families or anyone else on the tracks for this train wreck."

Along with previous bills to defund the health care law, House Republicans have also voted 37 times to repeal the law entirely.
