U.S. Rep. Michele Bachmann is among the 32 House Republicans who signed a letter to President Obama on Wednesday, urging him to request the resignation of Secretary of Health and Human Services Kathleen Sebelius because of glitches in the Affordable Care Act website, HealthCare.gov.

"With more than three years to prepare for the implementation of the Affordable Care Act, we are surprised to see the level of uncertainty, confusion and incompetence that has riddled the Health Insurance Marketplace since October 1," Bachmann and the other members write.

"Unfortunately, as we have seen in numerous news reports, many Americans have found it impossible to sign up for the required health coverage or to simply learn about the new plans and associated costs. The scope of the problem is so great that, were this a private company or military command the CEO or general would have been fired."

Democrats have also criticized the health care reform law's troublesome rollout. On Wednesday, U.S. Rep. Rick Nolan said it was time for Obama to "man up, find out who was responsible and fire them."

But, unlike Bachmann, Nolan stopped short of calling for the dismissal of any specific administration official or contractor.

"There are people like myself who supported the Affordable Care Act, but I'm not oblivious to the fact that this layout has done harm and damage to the brand," Nolan said.

The northern Minnesota congressman is among 11 House Democrats that Republicans are targeting with radio ads criticizing the website.

In the ads from the National Republican Congressional Committee, a woman says, "If you're facing all these issues just signing up, imagine how difficult it could be to get medical care. Finding a doctor's appointment will be a nightmare. And have you looked into how much your insurance premiums will rise?"

The ads are also running in the districts of U.S. Reps. Collin Peterson and Tim Walz.
