Harvard researcher Ari Ne'eman says the policy shifts underway under the Trump administration pose a unique threat to people with disabilities, but that they've fought for rights before and won.

At issue is a case testing the reach of federal laws that promise special help for children with disabilities in public schools. Specifically: What do parents have to prove in order to get that specialized help?

In Georgia and other states, the federal government oversees the treatment of people with mental illness and developmental disabilities, because the states have been unable to comply with the Americans with Disabilities Act and the subsequent Olmstead ruling.
