Just four doctors in America still perform third-trimester abortions, i.e. terminations of pregnancies at 6 months and onwards.
These doctors know they risk their own lives every day, according to After Tiller, a documentary shown at the Sundance Festival last weekend. They receive frequest death threats, and they can't forget what happened to Dr. George Tiller. In 2009, Tiller was killed outside a church in Wichita, Kansas.
One of the four, Dr. Susan Robinson, worked with George Tiller and spoke highly of him: "'We learned at his knee: Kindness, courtesy, justice, love and respect."
"People tell me every single day, 'Dr. Robinson, you've given me my life back,'" she told ABC. "For these women it is life or death. Many women try to self-abort."
In New Mexico, where Robinson works, all terminations are carried out at the doctors' discretion - including late-term abortions. Robinson says the fact that the women have made it to her clinic at all indicates they haven't made the decision lightly.
"If a woman comes to me, particularly if she struggles to get there, she's come from Canada or California...because she feels so strongly that she needs an abortion," said Robinson. "This woman has struggled with this decision."
Third-timester abortions account for around 1% of all terminations in the US. They're widely condemned, even by supporters of abortion rights: 79% of "pro-choice" Americans support banning them, according to Gallup.
