evidence: A Republican congressman has said that abortions should not be allowed even when the mother's life is at risk because of advances in "modern technology and science". Joe Walsh of Illinois told reporters on Thursday that "you can't find one instance" where it has been necessary to perform an abortion due to the risk to the mother's life, citing medical advances. [...] Walsh was speaking to reporters after defining himself as "pro-life without exception" during a debate with Democratic challenger Tammy Duckworth. Walsh was asked if he was saying it was never necessary to terminate a pregnancy to save a mother's life.
