Rep. Bart Stupak (D) of Michigan was initially opposed to the health care bill, leading a group of anti-abortion Democrats against it. But when President Obama offered to sign an executive order affirming that that no federal funds would be used for abortions under the bill, Representative Stupak and his group agreed to vote for it, raising the ire of opponents.
His change of stance made him the target of harassing and threatening phone calls, some of which his office released to CBS news.
One of the tamer calls released came from a woman who said: "There are millions of people across the country who wish you ill, and all of those thoughts that are projected on you will materialize into something that's not very good for you."
Stupak announced in April that he would retire at the end of his term, but insisted he was not being pushed out of office by the threats.
