President Donald Trump said Monday, Sept. 30 he signed Autism Cares Act into law after the lawmakers passed the legislation.

“Today, I was proud to sign the Autism CARES Bill! We support research for Americans with Autism and their families,” President Trump announced in a tweet. “You are not forgotten, we are fighting for you!”

Before going to the president’s desk for signature, the bill received broad support with 173 House members and 41 senators having signed on, according to PRNewswire.

The measure authorizes more than $1.8 billion in funding for autism programs at the Centers for Disease Control and Prevention (CDC), National Institutes of Health (NIH) and Health Resources and Services Administration over the next five years.

The funding primarily supports autism research grants awarded by NIH, which advances the scientific understanding of autism, expands efforts to develop treatments for medical conditions often associated with autism, and addresses the needs of people affected by it.

The Autism Cares Act of 2019 also reauthorizes and supports numerous programs across the United States focused on ensuring high-quality services for people with autism.

The CDC estimates that 1 in 59 U.S. children have autism, according to surveillance and prevalence studies authorized by Autism CARES.
