Newsnight: Abortion in the US political debate
22 August 2012 Last updated at 03:23 BST
Republican presidential candidate Mitt Romney has called on one of his party's own Senate candidates to pull out of a race in Missouri.
Representative Todd Akin told a local TV station on Sunday that women who are the victims of what he called "legitimate rape" could not get pregnant.
Mr Romney and his running mate Representative Paul Ryan quickly distanced themselves from the comments.
Kellie Rose-Ferguson, director of Republican Majority for Choice and Lila Rose, founder and president of the "pro-life" group Live Action speak to Newsnight's Gavin Esler about Mr Akin's comments and the place of abortion in the US political debate.
