Blunt, ahead of the vote, suggested that the amendment was necessary to help protect Americans from higher utility bills and "send a clear message" to President Obama.
 
"This vote is important to send a clear message to the administration that Americans simply can't afford to pay higher utility bills because of bad energy policies," he said. 
 
 
"When you put a price on carbon it works," she said. "If you look at my state, we are creating jobs in clean energy, we're balancing our budget better than we ever have before. ... So I don't know why on earth we would say 'no' to something that leads to prosperity."
