Republican senators are criticizing Health Secretary Robert F. Kennedy Jr.'s policies, particularly his unsubstantiated claim linking Tylenol to autism. Senator Bill Cassidy, along with others like Susan Collins and Lisa Murkowski, demand scientific evidence to support these claims, fearing negative impacts on pregnant women and public health. They express concern over pressure to approve vaccine recommendations despite lacking scientific basis. The backlash raises questions about the political fallout for President Trump and his administration.
