Marco Rubio, the Florida senator who ran an unsuccessful campaign for the Republican presidential nomination, has said women infected with the Zika virus should be denied abortions.
The ban should apply even if a woman had reason to believe that her child would be born with severe microcephaly - a developmental disorder that can result from Zika infection.
"I understand a lot of people disagree with my view - but I believe that all human life is worthy of protection of our laws. And when you present it in the context of Zika or any prenatal condition, it's a difficult question and a hard one," Rubio told Politico.
"But if I'm going to err, I'm going to err on the side of life."
Florida is the first state in the US in which cases have been discovered in people who have not travelled to countries confirmed to have been affected by the mosquito-borne Zika virus.
