Regarding the Feb. 15 news article “Disability rights advocates say bill would gut ADA”:

Sen. Tammy Duckworth (D-Ill.) lost both legs flying a Blackhawk helicopter over Iraqi battlefields. She pledged to protect the Americans With Disabilities Act from House “reform” Bill 620. But Republican senators outnumber Democrats and independents.

Even revered former senator Bob Dole (R-Kan.) came up short in December 2012 when he pleaded with the senators to ratify a U.N. treaty modeled on our ADA. Already 138 other countries had done so. Just five more U.S. senators were needed to ratify the U.N.’s version of our disability-rights law. It never happened.

Will enough senators make amends now and protect the ADA and their fellow Americans with disabilities?
