Anti-abortion advocates have expressed concern but not opposition to Robert F. Kennedy Jr.'s nomination as Health and Human Services secretary, despite his previous support for abortion rights.

WASHINGTON — Robert F. Kennedy Jr.’s anti-vaccine advocacy is outside the mainstream. His previous statements on abortion could alienate Republicans. But a new poll finds that not all of his controversial health goals are unpopular — in fact, at least one has broad support among Democrats and Republicans.

Robert F. Kennedy Jr. has said vaccines are not safe. His support for abortion access has made conservatives uncomfortable.

The time Robert F. Kennedy Jr. spent in New Hampshire as a presidential candidate became the subject of key moments during his U.S. Senate confirmation hearing on Wednesday.

RFK Jr. claimed he is not “anti-vaccine” and appeared unfamiliar with key aspects of healthcare insurance programs in his confirmation hearing.

In the three-hour hearing, Kennedy fielded questions on his interpretation of Title X, late-term abortions, mifepristone, stem-cell research and medical conscience rights.

Robert F. Kennedy Jr. faced intense scrutiny Wednesday on Capitol Hill as he sought confirmation for the role of Health and Human Services secretary.

If approved, Kennedy will control a $1.7 trillion agency that oversees food and hospital inspections, hundreds of health clinics, vaccine recommendations and health insurance for roughly half the country.
