What Donald Trump doesn’t want you to know about his plan to build a “Great Wall” between the U.S. and Mexico: He’d need to steal private property from Americans to build it.

In 2013, the federal government succeeded in using eminent domain to acquire the land rights to build a border fence across Dr. Eloisa G. Tamez’s ancestral home in 2013. Dr. Tamez’s land has been in her family since the King of Spain granted it to them in 1767. But it rests on the U.S.-Mexican border, so the Department of Homeland Security took it to erect a border wall under a federal law enacted during the Bush administration.

The Great Wall of Trump would mean hundreds, if not thousands, of Tamezes….

The Government Accountability Office reports ( PDF ) that “federal and tribal lands make up 632 miles, or approximately 33 percent, of the nearly 2,000 total border miles.” What of the remaining 66 percent? “Private and state-owned lands constitute the remaining 67 percent of the border, most of which is located in Texas.”

That means that if Trump’s plan to build another 1,000 miles of wall is carried to fruition, thousands more homeowners will see their property destroyed or partially walled-off.
