Then there are at least two cabinet members in the Trump administration who have attended the annual Bilderberg summit, where top globalists, politicians, bankers, communists, royalty, and crony capitalists meet once a year to plot policy behind closed doors and recruit useful idiots to their globalist cause. The first is former Texas Governor Rick Perry, a Republican who serves as Trump's energy secretary. The other is Secretary of Defense James Mattis, a military man who attended the 2015 Bilderberg meeting in Austria as a “distinguished fellow” of the Hoover Institution.

Maybe Mattis just wants another invite.
