Robert F. Kennedy Jr. made headlines this week as he faced a Senate panel for his confirmation hearing to become the next U.S. health secretary. While many Republicans seem to back him, his past stances on vaccines and abortion sparked heated discussions.

The Senate Finance Committee grilled him for over three hours, covering everything from Medicaid to a recent measles outbreak in Samoa. Known for his critiques of vaccines and the public health system, Kennedy couldn’t avoid addressing these controversial views. His distinctive voice, affected by a neurological condition called spasmodic dysphonia, also caught attention as he spoke.

One thing’s clear: Kennedy appears to have won over most Republicans. Senators who were on the fence, like Thom Tillis and Todd Young, asked questions suggesting they might support his nomination. However, his history with vaccine skepticism remains a sticking point for some.

The hearing was just step one. Kennedy will face another round of questions from the Senate Health, Education, Labor, and Pensions Committee on Thursday. All eyes are now on the Finance Committee, which will decide whether his nomination moves to a full Senate vote.

Stay tuned as this story unfolds—Kennedy’s confirmation journey is far from over.
