According to a Reuters report based on a review of an internal document produced by the Department of Homeland Security, President Trump’s proposed wall at the U.S.-Mexico border could cost as much as $21.6 billion and take more than three years to build. Trump has previously cited a $12 billion figure for the project and both House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell have said that it could cost as much as $15 billion. The report is expected to be presented to DHS Secretary John Kelly in the coming days.
