He's a professor in the economics department at George Mason University. ("...founded in principles that stress the value of free markets in promoting peace and prosperity.") GMU is partially funded and controlled by the Koch foundations.[1] He is a research fellow at the Mercatus Center. ("Mercatus research focuses on how markets solve problems.") Mercatus is funded by the Koch family and Charles Koch is on the board. He is an adjunct scholar at the Cato Institute ("The vision of the Cato Institute is to create free, open, and civil societies founded on libertarian principles.") Cato was founded by Charles Koch, as the Koch Foundation.

So expect to hear the Koch Industries position from this source.
