There's not going to be a bill, so Bush won't have to veto anything.
Not necessarily - if Congress is infringing on his war powers as Commander-in-Chief, there's not need for the Executive branch to obey un-Constitutional laws.
Congress is 99% of the freaking problem. The other 1% is made up of the people who don't realize that this issue is not currently controlled by the US government - it's a sale of unit of a British conglomerate to another conglomerate located in another nation that just happens to be the UAE.
Congress's role is to pass laws that ensure (and fund) security at the ports - anything beyond that is their penny anty bullshit attempt to have more control to this situation than they are empowered to. Makes for great news, but worthless results.
And as for an over-rideen veto - if the law violates a trade treaty that has been ratified it violates the constitution and Congress's photo-op actions can get tanked by an un-elected court here or somewhere else.
Focus on the issues at hand - ensuring national security. Push the Congrescritters to get to that issue and how it will be resolved instead of hoping for an instant gratification arm chair general response to an issue that nobody cared about when it was only the Chinese, Singapore, Brits, etc. that were "infiltrating" our ports.
