President Obama blasted Republican presidential front-runner Donald Trump in April, 2016 for his plan to bar immigrants in the U.S. from sending money back home to force Mexico to pay for a new border wall. Oh, no. It s Trump,  a smiling Obama said when he was asked about the 2016 candidate s latest comments.Obama called plan another shortsighted idea from Trump that could spark concern among world leaders.  I am getting questions constantly from foreign leaders about some of the wackier suggestions that are being made,  Obama told reporters at the White House.Obama said Trump s border wall proposal could have  enormous  economic consequences for Mexico, which receives billions of dollars in payments that immigrants in the U.S. send home, and possibly touch off a major spat with an ally. The notion that we are going to track every Western Union bit of money that s being sent to Mexico   good luck with that,  Obama said.Obama s remarks came after The Washington Post published a two-page memo from Trump outlining how he would get Mexico to pay for his wall. Trump s memo outlines how he would cut off certain remittances   cash transfers from people in the United States to Mexico   unless Mexico s government offered $5 billion to $10 billion to pay for the wall.Mexican President Enrique Pe a Nieto has said he won t pay for Trump s wall and claimed the candidate has damaged U.S.-Mexico relations.The country s former president, Vicente Fox, slammed the proposal, saying,  I m not going to pay for that f ing wall. Meanwhile, TMZ reported that workers are busy building a large wall around Obama s new DC residence where he will be moving from the White House, that was coincidentally, also surrounded by a massive wall.Why is it that politicians like Obama and even Republican Speaker of the House Paul Ryan, who has a two-decade-long history of promoting open borders immigration policies, have no problem building a border fence for themselves and their family, even as they denies the American people those same protections.They re quick to criticize Trump and his supporters for wanting to build a wall on our southern border to keep foreign intruders and criminals out for the sake of our national security, yet have no problem erecting large walls around their personal residences to keep their own families safe
