The calls placed to Stupak's office reveal the extreme anger members of Congress are facing.
"Congressman Stupak, you baby-killing mother f***er... I hope you bleed out your a**, got cancer and die, you mother f***er," one man says in a message to Stupak.
"There are millions of people across the country who wish you ill," a woman says in a voicemail, "and all of those thoughts that are projected on you will materialize into something that's not very good for you."
CBS News also obtained copies of faxes sent to Stupak, which include racial epithets used in reference to President Obama and show pictures of nooses with Stupak's name.
When the House was first considering health care legislation, Stupak led the fight to insert stringent abortion coverage restrictions into the Democrats' health care bill in the House. Last week, however, he agreed to support the Senate version of the bill, despite his objections to its language on abortion.
Stupak negotiated with Democratic leaders over the abortion language until the eleventh hour, finally agreeing to support the legislation when President Obama agreed to sign an executive order reaffirming the existing ban on federal dollars being spent on abortion.
Anti-abortion rights activists and Republicans said an executive order was not good enough since it can easily be reversed. Democrats, by contrast, maintain that the original Senate language did not allow taxpayer money to go to abortion.
Stupak said last week his life had become a "living hell" because of the onslaught of threatening messages he has received. Numerous other congressmen who backed the bill also report receiving threatening messages and seeing violent actions from citizens.
Yes, threats are despicable and should be denounced by all. But wouldn't it have been nice if CBS had informed readers that the "onslaught of threatening messages" he received last week were from those who supported the health care bill? Isn't it odd that CBS didn't cover this story last week?
