My take on this whole thing, is the Amazon basically wrote the entire scope...so they just thought they were going to win because only they would meet it (this was a bit of a scandal just a few months back.) They bid high, and then they lost. Now they are mad that their lobbying wasn't a 100% success, so they are suing. It's all so very Amazon.
It should be no surprise that he's pissed that that amount of investment isn't starting to pay dividends.
