Twice each year, the Koch family conducts strategy meetings with corporate and thought leaders to plan how to advance their "free market" ideology. ThinkProgress has the guest list and program for their June 2010 meeting (in Aspen), and, while immigration isn't mentioned, many of the known attendees are on the wrong side.

I don't normally recommend anything at ThinkProgress, but in this case I'll suggest taking a look at their post and downloading the PDF.

The New York Times has a related report here; from that:

The participants in Aspen dined under the stars at the top of the gondola run on Aspen Mountain, and listened to Glenn Beck of Fox News in a session titled, “Is America on the Road to Serfdom?” (The title refers to a classic of Austrian economic thought that informs libertarian ideology, popularized by Mr. Beck on his show.)The participants included some of the nation’s wealthiest families and biggest names in finance: private equity and hedge fund executives like John Childs, Cliff Asness, Steve Schwarzman and Ken Griffin; Phil Anschutz, the entertainment and media mogul ranked by Forbes as the 34th-richest person in the country; Rich DeVos, the co-founder of Amway; Steve Bechtel of the giant construction firm; and Kenneth Langone of Home Depot... The group also included longtime Republican donors and officials, including Foster Friess, Fred Malek and former Attorney General Edwin Meese III... Participants listened to presentations from the (US Chamber of Commerce), as well as people who played leading roles in John McCain’s presidential campaign in 2008, like Nancy Pfotenhauer and Annie Dickerson, who also runs a foundation for Paul Singer, a hedge fund executive who like the Kochs is active in promoting libertarian causes.

Malek currently raises funds for Karl Rove.

There's also a tea parties link: one of the June sessions was called "Mobilizing Citizens for November" ("Is there a chance this fall to elect leaders who are more strongly committed to liberty and prosperity? This session will further assess the landscape and offer a strategic plan to educate voters on the importance of economic freedom.") The hosts were Sean Noble (@snoble37), Karl Crow of Themis, Mark Mix of National Right to Work, and Tim Phillips of Americans for Prosperity. AFP has been a very active "facilitator" of the teaparty movement.

Those who spoke at the June meeting include Peter Schiff (bad on immigration), Stephen Moore (ditto}, and Michael Barone (ditto). Others are: Ramesh Ponnuru; Phil Kerpen and Jeff Crank of AFP; Peter Wallison and Arthur Brooks of the American Enterprise Institute, Russ Roberts and Veronique de Rugy of the Mercatus Center (associated with George Mason University; see the link); Gretchen Hamel; Charles Krauthammer; and Tim Carney of the Washington Examiner.

Those listed as attending past meetings include Haley Barbour (bad on immigration), John Stossel (ditto), Mike Pence (ditto), Bobby Jindal, Antonin Scalia, Clarence Thomas, Rush Limbaugh, Jim DeMint, Tom Coburn, Paul Ryan, and Tom Price.

Obviously, there's nothing wrong or that sinister about the Kochs holding meetings like these. And, George Soros and associates no doubt hold similar meetings with those on their side. However, just as Soros' loose borders policies no doubt "informs" the immigration policies that those who receive his money offer, the same is probably true of the Kochs' loose borders policies. Aside from DeMint, there are few above who might be considered "border hawks", and some of those listed are quite bad on that issue.

And, of course, this provides yet more evidence of how those in the supposedly grassroots tea parties movement are doing the bidding of the very rich, even if the teapartiers have been bamboozled into thinking otherwise.
