Might be on any attempt by the Congress to deny The United Arab Emirates the port contracts in the United States. Bush has said so:
Suzanne Malveaux, CNN White House reporter, said this about the President's public statements:
He would veto any legislation to hold up this deal and warned that the United States was sending mixed signals by going after a company from the middle east when they said nothing when a British company was in charge. He goes on to say that it is the lawmakers - members of Congress - that have to step up and explain why a middle eastern company is held to a different standard. He also took issue with a reporter's question aboard the plane saying what is the - kind of the politics of all of this - and he says that this is not a political issue.
It could be argued that having a foreign country (The UAE company is state run) in charge is different from having a foreign firm in charge (as in the British case). Given that Bush believes the country is at war it would seem appropriate not to outsource the security of U.S. ports.
How very odd this whole story turned out to be! The wingnuts are furious at Bush.
Added after some thought: Could this be Rove's plot to distance the Republicans in the Congress from an unpopular president? So that they'd retain control in 2006? I find that an appealing idea but I just can't see Bush going along with that. Though who knows.
