Washington (CNN) - Every Republican in the Senate now appears ready to revoke President Obama's signature health care law. This comes as a federal judge, in Florida, strikes down key parts of the law as unconstitutional.
The GOP holds 47 seats in the Senate.
According to Sen. Jim DeMint's office, 45 of them will co-sponsor the South Carolina Republican's legislation – introduced last week - to fully repeal the health law. Republicans are "standing with the American people who are demanding we repeal this government takeover of health care," DeMint said at the time.
DeMint's office told CNN it did not yet have confirmation that Mississippi Sen. Thad Cochran would sign on. But CNN contacted Cochran's office and confirmed that he would.
Chris Gallegos, a spokesman for Cochran, explained that the senator's legislative staff conducts a bill review first – before asking the senator whether or not to co-sponsor a bill.
"That process is going on in our office right now," Gallegos said. "We expect the senator to co-sponsor the DeMint bill."
Based on these numbers, that would mean that all of the Republican senators are now on board with the plan to repeal the health care law.
The intentions of some newly-elected GOP senators, who enjoy Tea Party support, are of little surprise. Marco Rubio of Florida, Mike Lee of Utah, Pat Toomey of Pennsylvania and Rand Paul of Kentucky have all denounced the health care law.
Some names that may stand out to some are moderate Republicans Olympia Snowe and Susan Collins, both of Maine, and Scott Brown of Massachusetts. However, all three voted against the law's passage.
President Obama recently defended the law after the House voted to repeal it in January.
"I'm not willing to refight the battles of the last two years," the president said at a Families USA's Health Action Conference in Washington, on Friday. But the president has acknowledged he is open to ideas on how to improve the law.
Jon Summers, spokesman for Senate Majority Leader Harry Reid, harshly denounced Republican efforts.
"What they are touting is their plan to raise taxes on small business, charge seniors more for prescription drugs, and increase the deficit," Summers said.
"We are happy to work with Republicans to improve the law, but we will not be part of their effort to stick it to consumers," he added.
Many Republicans acknowledge that their efforts to repeal the health care law could likely fail. They do not have enough votes to overcome a likely wall of Democratic opposition in the Senate. And, in the unlikely impossibility a GOP repeal bill passed the Senate, President Obama has the power to veto it.
