RFK Jr set to face abortion, vaccine scrutiny in sit-downs with senators on Capitol Hill

Kennedy is expected to spend four days on the Hill before lawmakers leave town for Christmas.

Sen. Markwayne Mullin, R-Okla., shared that while he will meet with Kennedy, he is already a resounding "yes." 

"I've had the privilege to already sit down and answer most of my questions. We will meet, but I was supportive of the president nominating him for it," he said.

"So, I was supporting before that even took place."

Mullin, a close ally of Trump, noted that he had spent significant time with Kennedy on the campaign trail.

Kennedy is a prominent vaccination skeptic and has expressed his own criticism of many popular shots. This has drawn criticism from some on both sides of the aisle, as vaccinations have been commonly relied on for preventing viruses in childhood and diminishing their spread.

"If vaccines are working for somebody, I'm not going to take them away," he promised. 

"So, I'm going to make sure scientific safety studies and efficacy are out there, and people can make individual assessments about whether that product is going to be good for them."

Sen. James Lankford, R-Okla., told Fox News Digital that he expects to meet with Kennedy. A staunch pro-life advocate, Lankford has previously said he had many questions about Kennedy's position on abortion.

A number of other Republicans have previously expressed to Fox News Digital their interest in talking to Kennedy about abortion.

At the same time, Kennedy has managed to appeal to some politicians with his plans to tighten food regulations and "make America healthy again." 

The longtime Democrat-turned-independent could potentially gain support from those on the Democratic side of the aisle, given that there is bipartisan backing for addressing food safety.

It's unclear with whom Kennedy will meet on Capitol Hill, but some Democrats have signaled that their doors are open. 

A representative for Kennedy declined to comment to Fox News Digital on the visits planned this week.
