Votevets.org organized the ad campaign to get the U.S. Senate pass energy and climate laws.
"If the groups running this ad would stop long enough to realize that Sen. Burr just introduced an energy bill that has the greatest offset on emissions, they might not have wasted so much money,” Burr campaign spokeswoman Samantha Smith said in a statement Thursday. “Sen. Burr is focused on finding real solutions to the disaster in the Gulf and a workable energy policy for our country that encourages economic growth and keeps Americans safe."
In all, the ads are targeting three senators and cost $11 million.
