What it does
A plain-language summary is coming. Here is the official summary from the Congressional Research Service:
Think Differently About Emergencies Act This act requires the Federal Emergency Management Agency (FEMA) and the Government Accountability Office (GAO) to report to Congress regarding assistance and resources provided by FEMA to persons with intellectual and developmental disabilities and the families of such individuals who are impacted by major disasters. Specifically, FEMA must report within 120 days of this act's enactment, describing the assistance and resources that FEMA provides to such individuals and families through states, localities, nonprofit organizations, and individuals. Further, FEMA and GAO must each (1) review such assistance and resources, (2) identify potential legal impediments to providing such assistance and resources, and (3) provide recommendations to Congress.
How Congress voted
This law passed by voice vote or unanimous consent, so there is no record of how individual members voted.
