“We write to express our continued concern and deep frustration over the Department of the Army’s lack of progress to date regarding the 43 debarment referrals involving individuals or companies with links to terrorist groups including the Haqqani Network and al Qaeda,” the letter stated. “Given the serious nature of these determinations, we strongly believe these cases continue to warrant special and immediate consideration from the Department of the Army.”

The recommendations to terminate work with a contractor were made by U.S. Central Command and the Department of Commerce and are then sent to the Army for review and to make a final decision on whether to pursue the contract.

“We strongly believe that these debarment referrals are sufficient to call into question the acceptability of doing business with the named individuals or companies,” the senators wrote.

The senators said they were also concerned that the Army was taking too long to make decisions on whether to contract or not.
