The Pentagon is planning to ask Congress for authority to reprogram more than $2.4 billion from other military programs into the counterdrug account in order to then take it right back out and move it to the wall project.

“The Department would need to reprogram additional funding into the account to reach the up to $2.5 billion that may be required for border security support,” said Christopher Sherwood, a Defense Department spokesman.

However, a reprogramming request must be approved by both Republicans and Democrats on the four authorizing and appropriating panels that oversee the Pentagon.

Such approval in this case is all but certain to fail. All it would take is one chairman or ranking member to say no.
