That's how I read it too. It would be the contractor's responsibility to keep the I-9s. However, the fact that this is a national sweep could indicate some Wal-Mart knowledge. An interesting story to follow.

Not necessarily. A national sweep could also mean that they have a national contract with the same cleaning contractor, which wouldn't at all be unusual.

Perhaps the exec referred to in the article actually had some stake in the cleaning company as well.
