Rep. Bart Stupak, D-Mich., is making the media rounds going after the "less restrictive" abortion language in the Senate health care bill than what the Democratic lawmaker proposed in the House.

On ABC this morning, Stupak claims that he and 11 other House members will not vote for the health care bill unless it includes more stringent language to prevent federal funding from going toward abortion services.

"I want to see health care pass. I agree... people are being priced out of the market. We must have health care but, boy, there are some principles and beliefs that some of us are not going to pass," he said. "We're prepared to take the responsibility. I mean, I've been catching it ever since last fall. Let's face it, I want to see health care. But we're not going to bypass some principles and beliefs that we feel strongly about."

Secretary of Health and Human Services Kathleen Sebelius countered Stupak saying that the bill is not about abortion, but about changing the health care system to ease the burden on families and small businesses facing skyrocketing insurance premiums.

"I hope that when the bill is in its final form and people have a chance to look at it, I think they will understand that this bill does not change the status quo on abortion," Sebelius said.
