"...The administration's review of the deal was conducted by the Committee on Foreign Investment (JOHN SNOW!) in the United States, a body that was created in 1975 to review foreign investments in the country that could affect national security. Under that review, officials from the Defense, State, Commerce and Transportation Departments, along with the National Security Council and other agencies, were charged with raising questions and passing judgment. They found no problems to warrant the next stage of review, a 45-day investigation with results reported to the president for a final decision.

However, a 1993 amendment to the law stipulates that such an investigation is mandatory when the acquiring company is controlled by or acting on behalf of a foreign government. Administration officials said they conducted additional inquires because of the ties to the United Arab Emirates, but they could not say why a 45-day investigation did not occur..."

Noice. It gets better.

When I was doing research, the Dubai Ports World site wouldn't load. I took a look at Dubia Ports World via the wayback machine. I saw that in 2004, Dubai Ports World (DPI) bought a company named CSX World Terminals, a division of CSX Corporation. Well, you'll never guess who used to be CEO of CSX Corporation...

I'll give you a hint. He's currently the chairman of the Committee on Foreign Investment. You remember them. They were the ones that decided DPI didn't need the mandatory 45-day review. Oh yeah, here's another hint, he's the Secretary of the Treasury.
