(CNN) The Trump administration is considering diverting around $7.2 billion in additional Pentagon funding for border wall construction, five times what Congress authorized, sources told CNN.

The additional funds would allow the government enough money to complete approximately 885 miles of new fencing by the spring of 2022, according to an administration official.

The Washington Post first reported on the administration plans to divert additional funds.

Citing internal planning figures obtained by the Post, the Trump administration will pull $3.7 billion in funding from military construction projects and $3.5 billion from counterdrug program funding for the southern border wall, which Trump hopes to tout in his reelection campaign.

"The Department of Defense has no new announcements with regard to border wall construction," said Pentagon spokesman Lt. Col. Chris Mitchell.
