The White House plans an announcement on autism
The event, scheduled for 4 p.m., will be closely watched by scientists and advocates.
Health and Human Services Secretary Robert F. Kennedy Jr. promised earlier this year to determine the cause of autism by September.
The announcement alarmed some experts because Kennedy has promoted theories that routine childhood shots cause the developmental disability.
Speaking at a memorial for Charlie Kirk on Sunday, Trump said “I think we found an answer to autism.”
On the flight back to Washington, he suggested that children receive too many vaccines.
“It’s like you’re shooting up a horse,” he told reporters.
