Next idea: Military builds wall

THE “M” STANDS for military, not Mexico.

President Trump now wants the Pentagon to foot the bill for his long-promised border wall, according to a report Tuesday.

Trump has privately petitioned congressional leaders — telling House Speaker Paul Ryan (R-Wis.) last week that the military should pony up the $25 billion needed to erect the massive divider, The Washington Post reported.

Also last week, Trump suggested several advisers that the Department of Defense fund his border barrier, according to the newspaper.

The funds were not in the omnibus spending bill Congress approved last week, a point Trump made as he reluctantly signed the legislation into law.

“National defense is a very important two words,” Trump said during a signing ceremony on Friday. “Because by having a strong border system, including a wall, we are in a position, militarily, that is very advantageous.”

Trump campaigned on the promise that he would build the structure and somehow make Mexico foot the bill.

“Build WALL through M!” Trump tweeted on Sunday, apparently referring to the U.S. military — not Mexico.
