But his campaign subsequently said Kennedy did not mean to support any federal limits on abortion.

“Today, Mr. Kennedy misunderstood a question posed to him by a NBC reporter in a crowded, noisy exhibit hall at the Iowa State Fair,” his campaign said. “Mr. Kennedy’s position on abortion is that it is always the woman’s right to choose. He does not support legislation banning abortion.”

A longtime advocate of what he calls “medical freedom,” Kennedy has been in the public eye in recent years largely for discussions about public health issues, in particular his stated doubts about mandates for vaccinations and some conspiracy theories about Covid-19, including widely condemned suggestions that the virus could have been engineered to spare Ashkenazi Jews and Chinese people.

In June in a town hall in New Hampshire, he called himself “pro-choice” and spoke in favor of legal abortion.

“I’m not going be in a position, put myself in a position, where I am going to tell a woman to bring a child to term,” he said at the time.

Limits on abortion have been widely discussed in the Republican presidential field. Former Vice President Mike Pence, for instance, has called for his fellow GOP presidential candidates to support a 15-week national ban.

Kennedy’s remarks come only days after voters in Ohio rejected a ballot measure that would have made it harder for the state’s voters to codify abortion rights in the state constitution in November.
