Sen. John Cornyn (R., TX) has introduced the Keep the IRS Off Your Health Care Act of 2013, which would not allow the IRS to "implement or enforce any provisions of or amendments made by the Patient Protection and Affordable Care Act (Public Law 111-148) or the Health Care and Education Reconciliation Act of 2010 (Public Law 111-152)."
The Senator's press release notes the following:
“The official who oversaw the targeting of tea party groups is now in charge of implementing Obamacare at the IRS. Now more than ever, we need to prevent the IRS from having any role in Americans’ health care.
"I do not support Obamacare, and after the events of last week, I cannot support giving the IRS any more responsibility or taxpayer dollars to implement a broken law.”
