Tom Harkin, D-Iowa, right, and House Majority Leader Steny Hoyer of Md., attend an event on Capitol Hill in Washington 26 Jul 2010 to celebrate the Americans with Disabilities Act U.S. President Barack Obama and U.S. lawmakers are commemorating the 20th anniversary of the Americans With Disabilities Act, a sweeping civil rights law that calls for equal opportunity for those with mental and physical disabilities. The law prohibits discrimination against people with disabilities, and regulates federal and local programs, transportation, public accommodations and commercial facilities. President George H.W. Bush signed the legislation into law on July 26, 1990.  Its requirements include architectural upgrades such as braille signs, ramps, handicap-accessible automatic doors and designated parking spaces.  The law mandates equal access for disabled people in jobs and government programs, and in public spaces such as shopping centers and movie theaters.  The speaker of the House of Representatives, Nancy Pelosi, is marking the occasion Monday afternoon, and that evening, Mr. Obama commemorates the law with a White House event.
