This comes as the Republican Party is expected to formally endorse Donald Trump’s proposal to build a wall along the U.S.-Mexico border. Members of the Republican National Convention platform committee successfully petitioned to have language calling for the wall added to the platform text Monday. The proposal has sparked significant opposition across the U.S. Experts have also cast doubt on the overall feasibility of Trump’s border wall. Meanwhile, Donald Trump is expected to name his running mate within the coming days, ahead of the Republican National Convention. He’s said to be considering Indiana Governor Mike Pence, New Jersey Governor Chris Christie and former House Speaker Newt Gingrich.
