Including funding in Homeland Security appropriations, the Administration has so far identified up to $8.1 billion that will be available to build the border wall once a national emergency is declared and additional funds have been reprogrammed, including:
About $601 million from the Treasury Forfeiture Fund
Up to $2.5 billion under the Department of Defense funds transferred for Support for Counterdrug Activities (Title 10 United States Code, section 284)
Up to $3.6 billion reallocated from Department of Defense military construction projects under the Presidentโs declaration of a national emergency (Title 10 United States Code, section 2808)
These funding sources will be used sequentially and as needed.
