During the final US presidential debate, the candidates clashed on the contentious issue of abortion with Democrat Hillary Clinton criticising Republican Donald Trump's "scare rhetoric".
Mrs Clinton promised to appoint justices to the Supreme Court who would uphold a woman's right to abortion laid out in the court's 1973 Roe vs Wade decision, while Mr Trump promised to appoint "pro-life" justices who would overturn the decision.

"I feel that the justices that I am going to appoint, and I've named 20 of them, the justices that I'm going to appoint will be pro-life. They will have a conservative bent," said Mr Trump.
Under existing law, Mr Trump said, "You can take the baby and rip the baby out of the womb of the mother just prior to the birth of the baby."
"Honestly, nobody has business doing what I just said, doing that as late as one or two or three or four days prior to birth," Mr Trump said.
Mrs Clinton said Mr Trump's "scare rhetoric is just terribly unfortunate."
Mr Trump said Roe vs Wade would be overturned if he succeeds in putting two or three pro-life justices on the Supreme Court.

Roe vs Wade was a landmark case in the US in 1973 that upheld a woman's right to abortion.
"This is one of the worst possible choices that any woman and her family has to make and I do not believe the government should be making it," Mrs Clinton said
Mrs Clinton also said she will defend Planned Parenthood [organisation that provides reproductive health services] and there can be regulations on abortion so long as the life and the health of the mother is taken into account.
The candidates squared off at the University of Nevada in Las Vegas for the last time before Americans go to the polls on 8 November.
Also on the topic of the Supreme Court, Mr Trump said he would appoint a judge who would protect US gun rights.
He has said in the past that Mrs Clinton wanted to "essentially abolish" the Second Amendment of the US constitution guaranteeing a right to bear arms.
Mrs Clinton said she supports gun rights, but wants additional regulations on guns, citing examples of children being hurt or killed in gun accidents.
"I see no conflict between saving people's lives and defending the Second Amendment," she said.
