In December 2010, Gentry joined the board of the Cato Institute. Gentry was placed on the board by Charles Koch and David Koch. Cato Institute chairman Robert Levy and president Edward Crane expressed concern that Gentry was a conservative rather than a libertarian, with Crane referring to Gentry as a "Republican activist" and "social conservative." Crane also expressed disappointment that Gentry had not involved Crane or other Cato Institute employees with Koch-sponsored donor events. In an opinion editorial posted on CNN.com, Gentry defended the Koch brothers against allegations that they wanted to compromise the political independence of the Cato Institute. In June 2012, as part of a settlement over the ownership of the Cato Institute, Gentry was removed from the board due to a provision that bars Koch employees from serving on the institute's board.
