According to The Associated Press:
The woman, whose name was not disclosed in court papers, has said she will borrow money for the abortion from friends and family but cannot afford to pay for transportation.
Under a policy adopted in July, Missouri's prison system does not provide transportation or security for inmates seeking abortions. The policy is based on a state law that prohibits the spending of public funds "for the purpose of performing or assisting an abortion not necessary to save the life of the mother."
State officials argued that their policy is reasonable because of the costs and security risks of transporting inmates outside for procedures the officials said are not medically necessary.
"It is not the prison that has imposed the burden, but the prisoner's violation of the law that resulted in her incarceration that has imposed the burden," Attorney General Jay Nixon's office said.
The state is appealing the judge's ruling.
The woman's attorney, James Felakos of the American Civil Liberties Union, said the woman is running out of time because she is 16 weeks to 17 weeks pregnant, and Missouri bars abortions after 22 weeks.
In court papers, the woman said she discovered she was pregnant shortly after being arrested in California in July on a Missouri parole violation. She said she tried to get an abortion in California but was transferred back to Missouri before it could be performed.
