R.F.K. Jr., Trump’s Health Secretary Pick, Is Set to Meet with Lawmakers

Robert F. Kennedy Jr., President-elect Donald J. Trump’s choice for health secretary, is set on Monday to begin a series of meetings with Republican lawmakers on Capitol Hill to make his case for a spot in Mr. Trump’s cabinet.

Mr. Kennedy will almost certainly be questioned about his longtime anti-vaccine advocacy. He has said that he does not want to take away access to vaccines, but has repeatedly questioned their safety, trying to link them to a rise in autism in children — a debunked theory.

On Friday, The New York Times also reported that a lawyer helping Mr. Kennedy vet appointees for the incoming Trump administration had petitioned the government to revoke its approval of the polio vaccine.

Senator Mitch McConnell, the Republican leader and a survivor of polio, could be a key vote in Mr. Kennedy’s confirmation bid. In a statement Friday that did not name Mr. Kennedy, Mr. McConnell suggested that the petition could jeopardize his confirmation.

“Anyone seeking the Senate’s consent to serve in the incoming administration would do well to steer clear of even the appearance of association with such efforts,” Mr. McConnell said.

Once nominated by a president, candidates for top-level positions in an administration must be confirmed by the Senate. Republicans will control the chamber, but their 53-47 majority means they can lose only a few votes and still confirm Mr. Trump’s picks.

Mr. Kennedy is set to meet with Senator Lisa Murkowski of Alaska, a more moderate Republican, and some physicians in the party’s conference, including Senator Roger Marshall of Kansas.

Mr. Kennedy, who ran for president as a Democrat and independent before dropping out of the race and endorsing Mr. Trump, will probably also be asked about views on abortion access.

Former Vice President Mike Pence has called on Republican senators to reject Mr. Kennedy, citing his record of support for abortion rights.

“On behalf of tens of millions of pro-life Americans, I respectfully urge Senate Republicans to reject this nomination and give the American people a leader who will respect the sanctity of life as secretary of Health and Human Services,” Mr. Pence said in a statement.
