Wounded Soldiers Told They Owe Money to Army ... 'I didn't get paid for four months.'

ABC News: 'Nightline' Investigation: Wounded Soldiers Told They Owe Money to Army: "It started with a phone call from his wife, home with their four children. She didn't have enough money to pay the bills.

'And she was like, well, we haven't been paid,' Simpson said. 'And you know, instantly I was like, I don't know what to do. You know, I'm still in the hospital. I can't actually get up and go around and talk to these different people.'

And until 'Nightline' inquired at the Pentagon, Simpson said he could not find out what happened.

'Every day is something different,' he said. 'Well, this person isn't in. I'll have them call you back, give it a couple days. Couple days go by, I call back, well I got somebody else for you to talk to. And days lead to weeks, and weeks lead to months.'

It turns out the Army had mistakenly continued to pay Simpson a combat duty bonus while he was in the hospital.

He had been overpaid thousands of dollars, and the Army wanted the money back.

'By law, he's not entitled to the money,' said Col. Richard Shrank, 'so he must pay it back.'

Shrank said although that is the law, soldiers can apply for debt forgiveness if they believe the debt is a mistake. So far, more than 800 soldiers have done so. More than 600 of those requests have been granted, amounting to more than $600,000.

So, the Army said it withheld the paralyzed soldier's pay until it got back the amount he owed — with no advance notice, Simpson said.

'Four months,' he said. 'I didn't get paid for four months.'"
