The League of Conservation Voters says it will campaign against Minnesota Rep. Michele Bachmann in this fall election.
The non-profit advocacy group has named Bachmann to its national list of so-called "dirty dozen" congressional candidates. The list was created with an online vote, where Bachmann received 60 percent of the votes.
The non-profit group's Tony Massaro said Bachmann voted against energy legislation that would create clean jobs in Minnesota.
"She said she wants the people of Minnesota to be 'armed and dangerous' over energy reform, has called global warming 'voodoo, nonsense, hokum and a hoax,'" Massaro said. "This puts her in the category of global warming deniers."
Bachmann campaign director Gina Countryman said the nonprofit is a fringe group that won't influence Minnesota voters.
"Congresswoman Bachmann's focus on an all-of-the-above energy approach, that will increase the supply of clean and affordable American-made energy, and opposing things like cap and trade, that will not help the environment and will in fact hurt the economy," Countryman said.
The League of Conservation Voters says it usually spends hundreds of thousands of dollars in campaigns against those its national list of congressional candidates.
