Trump and RFK JR on astronomical rise of Autism

Trump has now vowed to get to the bottom of the skyrocketing Autism rates along with RFK JR.

The CDC's statistics show that in just one generation Autism rates went from 1 in every 10,000 to 1 in every 34.
This is an astronomical amount.
How is this happening?
Are vaccinations causing this?
Why did Fauci never address this?
RFK JR knows the truth and Trump is giving him the green light to bring it to light.
