Mexico has insisted it won’t pay for President-elect Trump’s promised border wall, but Mexicans living in the United States might.

Trump has been accused of breaking a key campaign promise by asking Congress to fund the wall through the appropriations process. He had vowed to build the “big, beautiful wall” along the U.S.-Mexican border at Mexico’s expense and is still suggesting funds appropriated by Congress for the wall will be reimbursed at a later date.
