The reports suggest that the administration will take $3.5 billion from the Department of Defence's counterdrug program, while another $3.7 billion from military construction funding.
The move would bring the total amount of federal funds allocated to border fencing to $18.4 billion under Trump, who made the border barrier a priority during his campaign for the presidency in 2016.
A federal district court in El Paso, Texas, ruled last month that the White House broke the law when it commandeered funds for the border wall that had been authorized by Congress for another objective.
The military projects that lost funding to the border barrier in 2019 included schools on military bases at home and overseas, as well as repairs to military installations in Puerto Rico that suffered damage from Hurricane Maria. The funding plans would reportedly give the government enough money to complete almost 900 miles of fencing by spring 2022, though a large portion of that would likely replace existing barriers. In 2019, the White House diverted $2.5 billion from counternarcotics and $3.6 billion from military construction funding for Trump's ambitious project.
As in years past, Trump will take money from two parts of the Pentagon budget. The Jan. 8 ruling overturned a federal district judge's order that blocked the money - a temporary win for the president pending further appeals.
The Supreme Court of the United States in July ruled that the president had the authority to take the decision. Originally, the completed barrier was to be 509 miles long.
In September, CNN reported that the Trump administration was discussing diverting more money from the Pentagon budget to constructing the border wall, a USA official familiar with funding of the project told CNN at the time.
Last Friday, the Trump administration announced it had completed 100 miles of barrier along the southern border.
