Three senators this week introduced a bipartisan amendment to help prevent toxic drywall from entering U.S. markets. Sens. Mark Warner (D-Va.) and Bill Nelson (D-Fla.) have cosponsored David Vitter’s legislation. Since Hurricane Katrina, many homes in Louisiana were rebuilt with toxic Chinese drywall, leaving homeowners with few options to remedy the situation. The amendment has cleared any Republican objections and awaits approval by Democrats to allow it to pass by unanimous consent.
