Robert F. Kennedy Jr., a vaccine critic who endorsed President Donald Trump after abandoning his own presidential bid, inched closer to becoming U.S. secretary of Health and Human Services with the Senate scheduled to vote on his confirmation on Thursday.

The vaccine critic is poised to be confirmed and pursue his agenda of fighting chronic disease even while pushing through the administration’s cost cuts.

The Senate voted along party lines to advance the nomination of Robert F. Kennedy Jr. for health secretary to the floor for a final vote, likely Thursday.
