Presidential hopeful Donald Trump has said US abortion laws should remain unchanged, although he believes the procedure amounts to murder.
In an interview with CBS News, Trump said: "The laws are set. And I think we have to leave it that way".
His comments come as Trump has struggled this week to articulate his position on abortion.
He withdrew a call for women who have abortions to be punished, only hours after suggesting it.
After an outpouring of criticism from both anti-abortion and abortion rights activists, Mr Trump later said only the people who perform abortions should face punishment.
The comments end a rocky week for Trump on campaign trail.
According to some polls, he is trailing Texas Senator Ted Cruz by 10 percentage points in Wisconsin, which hold its primary on Tuesday.
Democratic presidential candidates Hillary Clinton and Bernie Sanders and his Republican rivals Cruz and John Kasich repeatedly criticised Trump's shifting comments on abortion.
Cruz said the remarks showed that Trump "hasn't seriously thought through the issues".
Kasich - the popular governor of Ohio - also questioned whether Trump had the temperament needed for the office of the president.
The Republican front-runner supports a ban on abortions, with some exceptions.
Only the Supreme Court or a constitutional amendment has the power to overturn Roe v Wade and make abortion illegal.
It was unclear from his comments to CBS whether Trump would no longer support appointing justices that would overturn Roe v Wade. He previously had said he would.
Once a Democrat, Trump has been criticised for supporting abortion rights in the past.
Anti-abortion activists traditionally have avoided placing blame on women who undergo abortions, but have focused on those who perform the procedure.
