An Outside political interest group founded with support of the controversial Koch bothers is back on the attack in Alaska, targeting Sen. Mark Begich after his campaign blasted the group for “stalking off, tails between their legs,” after the group yanked more than $100,000 in television ad spots following the shutdown by Koch Industries of the Flint Hills refinery.

The implication by the Begich campaign -- strongly denied by Americans for Prosperity -- is that the conservative group was left shamefaced by the Koch connection and pulled the ads in order to keep a low profile until the dust settled.

On Monday, the Virginia-based organization launched a three-week, statewide media blitz that will cost just over $400,000, featuring a television commercial attacking Begich over the concept of a carbon tax. “We’re roaring forward like an Iron Dog,” said Russell, riffing on Begich’s canine analogy during a season of sled dog races and snowmachine contests.

"The latest Koch brothers political attack lasted a single day on TV before an independent fact check organization recognized Mark Begich opposes a carbon tax and declared the ad false,” Croes said in an email.

He added: “The Koch brothers and their dark money allies will stop at nothing in their repeated attempts to mislead Alaskans.” They’re trying to “divert attention from Alaskans' widespread opposition to them closing the Flint Hills refinery, laying off 80 Alaskans and dragging their feet on cleaning up contaminated drinking water.”
