Can anybody verify this for me?

This article is saying that the White House knew about the levees breaking and didn't tell anyone.

I'm putting it up here because I don't have the time to check it out, but I don't want to forget to check it out later. This should be on every news channel, but it's the first I've heard of it.

What have you heard?
