Sen. John Barrasso slammed President Obama on Monday after the White House confirmed it is extending the ObamaCare signup deadline for six weeks due to problems with the law’s website, telling Fox News’ Greta Van Susteren “this is a law that the president continues to figure isn’t the law.”

“He continues to make changes,” Barrasso said on “On the Record.” “This is about the 14th time he’s made some change in the law… If we’re going to make changes in the law, we ought to do it legislatively without the president just deciding that he can do it.”

Barrasso, R-Wyo., said he supports completely abolishing the law’s individual mandate, and any legislation that would give Americans the opportunity to delay the mandate and its new tax penalties for a year.

Barrasso also said he wants HHS Secretary Kathleen Sebelius to resign over the website’s issues, saying the botched ObamaCare rollout has ruined her credibility with the American people.

“I think when Jon Stewart and Saturday Night Live are making fun of the job that you are doing and the website, you know, what that speaks to is that young Americans are laughing at the secretary and the website,” he said.
