As Robert F. Kennedy Jr. prepares for Senate confirmation hearings as Health Secretary nominee, he faces intense scrutiny from both parties. Caroline Kennedy condemned him in a letter as a 'predator' unfit for the role, citing his discredited vaccine views and past substance abuse. With open concerns from Republican senators like Bill Cassidy and James Lankford, Kennedy's positions on vaccines, abortion, and health regulations are under fire. He aims to woo some Democrats and has garnered support from others, including cousin Patrick J. Kennedy. Uncertainty surrounds his potential as leader of the $1.7 trillion HHS agency.
