It was linked in an article about Hunter. He's the only member of Congress to publicly state what his earmarks are. The largest was a contract to find ways to counter IEDs. I don't consider that pork.
Pork is often defined as any expenditure/allocation that (a) directs tax dollars back to the sponsor's home district: and (b) couldn't get passed if it had to stand on its own. I don't know the details of this particular piece of bacon, but I suspect that DH has spun this as the most important piece of legislation in generations.
Also, please give me a link to where I can find HD's public disclosure of his pork allocations.
