According to a report in Reuters, based on a review of an internal document produced by the Department of Homeland Security, Donald Trump’s proposed wall at the U.S.-Mexico border could cost up to $21.6 billion and take more than three years to make.
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 up to $15 billion.
The report looks at the cost and timeline for building a physical barrier of walls and fences along the currently unsecured sections of the U.S.-Mexico border – a little more than 1,250 miles. Homeland Security Secretary John Kelly is set to receive the report in the coming days, according to Reuters.
Both Kelly and Trump have said that construction on the wall would begin in a matter of months, and have waved off concerns over the project’s price tag. In an interview with Fox News earlier this month, Kelly said he expected funding for the wall to come “relatively quickly.”
“I think the funding will come relatively quickly and like I said, we will build it where it’s needed first as identified by the men and women who work the border,” he said.
Kelly also said during the interview that he hoped the project would be completed within two years – significantly quicker than the DHS report estimates.
