Ryan, Cantor, and Martinez Address Koch Brothers Summit

Former GOP vice presidential nominee Paul Ryan, House Majority Leader Eric Cantor, and New Mexico Gov. Susana Martinez were among the featured speakers at a semi-annual summit organized by the billionaire Koch brothers.

Citing a source who attended the invitation-only event just outside Albuquerque, N.M., Politico reports that participants discussed the upcoming Republican Senate primary challenges to incumbent Senate Minority Leader Mitch McConnell of Kentucky and Sen. Mike Enzi of Wyoming.

But the source also told the publication that no consensus emerged with respect to the challenges — in Enzi's case by Liz Cheney, daughter of former Vice President Dick Cheney.

Politico reported that Cantor and Ryan appeared to have been well received by the largely wealthy audience of Republican donors.

Charles and David Koch's twice-yearly summits have featured past attendees such as Supreme Court justices Antonin Scalia and Clarence Thomas, media celebrities Rush Limbaugh and  Glenn Beck, and the late Andrew Breitbart, who died March 1, 2012.

In addition, Govs. Chris Christie of New Jersey, Bob McDonnell of Virginia, and Rick Perry of Texas have attended the Koch's summits.

An Albuquerque TV station reported the most recent conference appears to have taken place at the Hyatt Regency Tamaya Resort in Bernalillo, N.M., which was completely booked. Its entrances were blocked to traffic, the station said.
