Why is Fossella refusing to co-sponsor the Veterans Guaranteed Bonus Act

On October 10, 2007, Rep. Jason Altmire introduced a bill entitled the Veterans Guaranteed Bonus Act, HR 3793. The summary of his bill explains its intent;

To amend title 37, United States Code, to require the Secretary of Defense to continue to pay to a member of the Armed Forces who is retired or separated from the Armed Forces due to a combat-related injury certain bonuses that the member was entitled to before the retirement or separation and would continue to be entitled to if the member was not retired or separated.

Currently the bill has 219 cosponsors, enough to pass the bill if it comes to the House floor for a vote. Missing from that list of supporters is Rep. Vito Fossella. For forty-two days now Vito Fossella has refused to cosponsor this and the only question his constituents can ask is why? What exactly is Vito Fossella opposing; This is what Vito Fossella doesn't want to change that 219 Congress members are trying to fix;

The U.S. Military is demanding that thousands of wounded service personnel give back signing bonuses because they are unable to serve out their commitments. [via KDKA CBS]

We deserve someone in Congress who wil represent our interests. We deserve someone who supports our troops both in battle and after they return home, not someone like Fossella who sides with the government in trying to take away their money for getting injured.

update I edited a sentence in that third to last paragraph that was not reading well
