Enter the Libre Initiative, an organization that has collected millions from the Kochs' political network. Libre, which is pronounced LEE'-bray and means "free," pushes a message of limited government and economic freedom between lessons on how to build family-run businesses and prayer breakfasts with Hispanic pastors.

Its organizers pitch conservative ideals while offering tutorials on U.S. immigration law, support for overhauling the broken immigration system that stops short of campaigning for the Senate's bipartisan bill and collecting donations for the unaccompanied children crossing the United States-Mexico border illegally.

In effect, it is a shadow GOP — one with a gentle emphasis on social services and assimilation over a central party often seen as hostile to immigrants and minorities.

"We've gone to areas that other conservative organizations don't typically go," said Libre's Texas director Rafael Bejar, who helped distribute candy-packed Easter baskets at a San Antonio elementary school. Tucked in with the sweets: a pamphlet in English and Spanish noting that the national debt is approaching $17 trillion.
