Possible Use of FY2020 Defense Funds for Border Barrier Construction: Context and Questions [January 16, 2020] [open pdf - 962KB]
From the Document: "On January 13, 2020, the 'Washington Post' reported that the Trump Administration plans to reallocate $7.2 billion in Department of Defense (DOD) appropriations to construct barriers along the U.S.-Mexico border. Of this amount, $3.7 billion would reportedly come from deferring congressionally approved military construction (MILCON) projects. An additional $3.5 billion would be redirected through DOD's Drug Interdiction and Counter-Drug Activities account (hereafter 'counter-drug transfer account'). If the Administration were to carry out the actions as described by the 'Washington Post,' DOD would be using the same authorities it exercised in FY2019, when it transferred $6.1 billion in defense funds for border barriers. In this case, FY2019 and FY2020 defense funding for border barriers would total $13.3 billion."
