Robert F. Kennedy Jr. is President Trump’s choice to lead the Department of Health and Human Services. On Wednesday, he has his first confirmation meeting in front of senators. On Thursday, he will go before the Senate Committee on Health, Education, Labor, and Pensions.

There was a lighthearted moment during the hearing when RFK Jr. said he did not plan to prevent Americans from things like McDonald’s or Diet Coke, joking that he knows President Trump also occasionally indulges in those items.

RFK Jr: “I don’t want to take food away from anybody. If you like a McDonald’s cheeseburger, Diet Coke, which my boss LOVES, you should be able to get them.”

WATCH:

RFK Jr. met with Republican senators in December after Trump nominated him in order to convince those skeptical of his past positions that he would fulfill the president’s vision for HHS. Kennedy is one of the most high-profile figures nominated by Trump for his Cabinet. At the time, GOP sources said they believed he is in a strong position ahead of his hearings.

“He’s in a good spot. You haven’t really heard much consternation about his nomination at all in recent weeks,” one Senate GOP aide told The Hill.

The aide added that GOP senators expect that Kennedy will focus on “Make America Health Again” issues and that he no longer supports liberal abortion policies.

“If that turns out to be true, I think he’ll be on a glide path to being confirmed,” the aide said.

That said, an organization that former Vice President Mike Pence founded had launched a pressure campaign earlier this month to convince Republican senators to reject RFK Jr. Pence — who served as Trump’s vice president in his first term — is opposed to RFK Jr. due to his previous support for abortion.

“Whatever the merits of RFK Jr’s Make America Healthy Again initiative—indeed, whatever other qualities a nominee might possess—an HHS Secretary must have a firm commitment to protect unborn children, or else bend under the pressure and pushback surrounding these daily, critical decisions,” Advancing American Freedom President Tim Chapman and Board Chairman Marc Short, Pence’s former chief of staff, wrote in a letter to senators.

“While RFK Jr. has made certain overtures to pro-life leaders that he would be mindful of their concerns at HHS, there is little reason for confidence at this time,” they wrote.
