U.S. Rep. Kathy Castor (FL-14) is demanding the resignation of Health and Human Services Secretary Robert F. Kennedy Jr., citing what she calls a “serious threat to America’s public health” due to his leadership. Castor condemned Kennedy’s “complete disregard for facts and basic science,” warning that his actions “will cost lives.” She pointed to his dismantling of public health infrastructure, mass firings at HHS, and efforts to undermine vaccines and lifesaving research as clear evidence of his unfitness.
