The document discusses the Americans with Disabilities Act (ADA) which was signed into law in 1990 by President George H. W. Bush. It aims to eliminate discrimination against individuals with disabilities. The ADA estimates that around 43 million Americans have a disability. It defines a person with a disability as someone who has a physical or mental impairment that substantially limits a major life activity, has a record of such impairment, or is regarded as having such an impairment. The ADA also requires that public facilities like stadiums provide accommodations for disabled individuals such as wheelchair seating and accessible entrances.
