Trump Explains How He'd Pay for a Border Wall

Donald Trump said he will cut off money that immigrants in the U.S. send home to Mexico in order to force the country to pay for the wall he has proposed to build along the Mexican border.

Trump detailed his plan for the first time in a memo sent to the Washington Post, the newspaper reported on Tuesday. The Republican frontrunner said he would change a rule under the USA Patriot Act antiterrorism law to limit remittances sent to Mexico, unless the country agreed to pay for the wall.
