WASHINGTON — The Senate health committee approved two Trump administration nominees for key health roles Thursday, including the director of the Centers for Disease Control and Prevention and a pandemic preparedness leader, after an earlier vote was delayed.

The vote on Erica Schwartz for CDC director was approved by all Republicans and by Tim Kaine (D-Va.), with other Democrats opposed. Sean Kaufman won support from all Republicans to be assistant secretary for preparedness and response, and all Democrats were opposed.

Schwartz’s confirmation was all but assured after both health committee chair Bill Cassidy (R-La.) and Kaine expressed support. But Kaufman’s fate had been more of a question mark, after Cassidy clashed with him during his confirmation hearing over his past remarks questioning vaccine safety, which were first reported by STAT.

But on Thursday, Cassidy said he would approve Kaufman. “America is facing serious public health challenges,” Cassidy said, naming vaccine preventable diseases and an Ebola outbreak in parts of Africa. He said there’s a need to strengthen the nation’s pandemic preparedness.

Their nominations now move to the full Senate floor, where they are likely to be confirmed.

Cassidy said that his approval of Kaufman comes with conditions and that any departure from these agreements by the Health and Human Services Department could hold up further health nominees.

“Now we know that some individuals in HHS may continue to make decisions undermining confidence in vaccines and public health,” Cassidy said, seemingly alluding to health secretary Robert F. Kennedy Jr. and his allies, without naming anyone.

Among those agreements, Cassidy said, are personnel changes at HHS and not allowing Kaufman to be involved in vaccine policy decisions.

He also suggested further changes could be coming to a CDC website that was modified by Kennedy to reverse the agency’s stance that vaccines do not cause autism. But even after some modifications, it still raises unsupported questions about a possible link between shots and the disorder.

Last week, Cassidy said the page had been changed as a sign of “good faith.” But he later criticized the minimal changes as “almost an insult to the American people” in a CNN interview.

“The administration is committed to continuing the work to remove vaccine misinformation from that website. This is something again that I’ll pay close attention to,” he said Thursday.

The approvals are a win for President Trump and for health secretary Robert F. Kennedy Jr., whose department has been plagued by vacancies in key public health roles as the country confronts a number of public health crises, including measles outbreaks and a foodborne parasite crisis.

It’s likely one of Cassidy’s final health-related confirmation votes, after he lost his reelection bid following public criticism from Trump and Kennedy, who blamed the senator for blocking their Make America Healthy Again agenda.
