Why is everyone acting as if this port deal is the President's idea? I have not seen anyone discuss who is on the interagency boards that reviewed and approved this deal. Try looking that up, and stop acting like we live in a dictatorship.
Everyone's acting that way because he can stop it, all by himself. And should. And hasn't. And HAS made a veto threat to protect the deal...one of the strongest--and only--veto threats he's ever made.
As to 'looking it up,' see here for more info on the CFIUS. What a joke.
