Unfortunately for Walker, that endorsement doesn't necessarily include the backing of Americans for Prosperity, the massive grass-roots political operation that in 2014 rivaled the political parties in scale. According to the Times' Nicholas Confessore, the Kochs told those in attendance that they would not intervene in the primary on Walker's behalf through their subsidiary groups.
Update: In a statement, David Koch said that his comments did not constitute an endorsement. "While I think Governor Walker is terrific," he said, "let me be clear, I am not endorsing or supporting any candidate for President at this point in time." (We updated the headline, too, to reflect this clarification.)
Walker also sat down with former Fox News host Glenn Beck, earning a not-quite-endorsement from the one-time conservative media star.
As exhaustively detailed at Breitbart News, Beck and Walker also discussed immigration. Walker's comments struck a strongly protectionist tone, including suggesting limiting legal immigration. "In terms of legal immigration," he said, "how we need to approach that going forward is saying ... the next president and the next Congress need to make decisions about a legal immigration system that’s based on, first and foremost, protecting American workers and American wages."
Those comments prompted a harsh response from GOP consultant Liz Mair, who resigned from Walker's campaign earlier this year after tweets critical of Iowa came to light. On Monday, Mair tweeted:
In following tweets, she made clear which "former boss" she was referring to.
Walker has come under fire for changes in his position on immigration previously. Last month, he appeared to soften a firm "no amnesty" position he had been outlining on the trail. His comments to Beck used that line explicitly.
But still. Losing Mair and gaining the Koch brothers is not a bad Monday at all. Walker probably just wishes he hadn't gained the "Olympics" line, too, which will probably appear in a campaign spot near you sometime soon.
