Billionaire David Koch (see Koch family) joined with George Soros, the Ford Foundation, and the Rockefeller Foundation to each give the American Civil Liberties Union $10 million to fight the PATRIOT Act [1]. Reasonable people can disagree on the PATRIOT Act, but fighting it or trying to reform it was probably the correct thing to do.

Whatever the merits of opposing the PATRIOT Act, giving money to the ACLU is never the correct thing to do.

The ACLU is a far-left group that strongly supports and enables illegal immigration and that's even collaborating with the Mexican government in furtherance of illegal activity. Giving the ACLU money to fight the PATRIOT Act frees up resources for other areas, such as litigation designed to enable illegal immigration. Reasonable people can disagree with various other issues the ACLU involves themselves in, but there really should be no debate about them joining with a foreign government in order to enable illegal activity inside the U.S.

And, it's not like David Koch didn't have other options: there are groups like the ACLU on his side of the fence. Instead, he gave money to a far-left group that's collaborating with the Mexican government, joining with Soros, the Ford Foundation, and the Rockefellers. Someone has to fill the gap left by David Gelbaum, right?

[1] Nick Gillespie of Reason Magazine - part of the "Kochtopus" - highlights the $10 million as if it's a good thing:

That links to the undated lasocialdiary.com/node/125921 which says:

I think [David Koch has] committed more than $440 million to various philanthropies and projects asides from high culture. He’s politically conservative. He and his brother Charles, along with George Soros, the Ford Foundation and the Rockefeller Foundation each contributed $10 million to the ACLU to defeat parts of the USA Patriot Act.

That's undated but it also says "Last Tuesday night the New York City Ballet launched its 2008-2009 season".

Gillespie's post also links to a post at "Faces of Philanthropy" (facesofphilanthropy.com/david-h-koch; their site is down at post time) dated April 1, 2010 containing this:

David Koch has remained an advocate of libertarian ideology of minimizing government role and maximizing private involvement in the economy. He has contributed hefty sums to Cato Institute, Citizens for a Sound Economy, and the Institute for Justice, the Reason Foundation, the Heartland Institute, the Libertarian Party, the Pacific Research Institute for Public Policy, and the George Mason University.
* David Koch has also contributed to the development of the arts and communications. He pledged over $100 million for the renovation of the New York State Theater. He is also one of the biggest corporate donors for the Public Broadcasting Service (PBS) show Nova.
* David Koch has also contributed $10 million to the ACLU in relation to crushing Parts 15, 16 and 17 of the US Patriot Act.
