Some GOP senators want public commitments from Robert F. Kennedy Jr. before deciding whether to support him as the next secretary of the Department of Health and Human Services, signaling that President Donald Trump’s pick will have to win over uncertain Republicans in order to secure the job.

Kennedy, a Democrat who ended up supporting Trump in the 2024 presidential campaign, faced a confirmation grilling Wednesday over his controversial views -- on everything from vaccines to abortion -- that have both Republicans and Democrats raising concerns.
