The Defense Department has identified $12.8 billion in possible funding that it could use to fulfill President Trump's call for a border wall.
Sen. Jack Reed, D-R.I., released the 20-page spreadsheet on Twitter Monday night.
Trump last month declared a national emergency at the border, and said he wants to use $3.6 billion for border wall projects.
The Pentagon's list said it has found possible funding sources that are "in excess of the amount needed."
But it's not clear which projects the Defense Department will draw from. Some states that have been allocated big chunks of money that haven't been spent could see a hit.
