DENVER (AP) -- Supporters of a climate change bill before Congress are urging Colorado's Democratic senators not to weaken the legislation.
Members of groups including Environment Colorado and the Denver Area Labor Federation as well as former residents of New Orleans will gather outside Sen. Michael Bennet's office to back the bill and mark the fourth anniversary of Hurricane Katrina. They also plan to visit Sen. Mark Udall's office.
The bill, which narrowly passed the House earlier this summer, imposes the first limits on greenhouse gases. It eventually would lead to an 80 percent reduction by putting a price on each ton of climate-altering pollution.
Senate Democrats say changes will be necessary in order for the bill to pass.
