The Trump administration is considering alternative ways to pay for the border wall, backtracking on the president's oft-repeated promise that Mexico would foot the bill.
A White House spokesman said one idea taking shape is to apply a 20 percent tax on imports from Mexico, as well as other countries with which the U.S. has a trade deficit. That would effectively saddle U.S. consumers with a significant portion of the wall's cost, estimated at $15 billion or more.
