Glen Beck is Mormon...like Romney. NWO is made up of Freemasons...so is the Mormon Church, see all cymbals on their Churches.
Now, the North American Union (USA, Canada, & Mexico) is the plan of the NWO...that means NO BORDERS period. That Plan is online along with the North American Highway for trade...also do not want borders to inhibit trade among the nations....like European Union and African Union. That is why there will never be a border fence.
Also, illegal aliens (most of whom are somewhat illiterate or poorly educated) are the only growth area the LDS church has right now and conversion from Catholicism to Mormonism is pretty common as well. It isn’t surprising they have backed illegal immigration.
