LIVE | Trump & RFK Jr. drop bombshell on autism causes

A White House announcement about autism is expected Monday afternoon after President Donald Trump’s weekend comment that “I think we found an answer” to the developmental disorder. Health Secretary Robert F. Kennedy Jr. promised earlier this year to determine the cause of autism by September. But brain experts say there is no single cause, and the rhetoric appears to ignore decades of science into the genetic and environmental factors that can play a role. Autism rates are rising, but that’s largely about an expanded definition, more awareness and more screening. Science has shown that autism is mostly rooted in genetics.
