[EX Q]: UNITED NATIONS (Reuters) - The United States will seek to boost its case for United Nations action against Iran when Security Council envoys visit Washington on Monday to view pieces of weapons that  U.S. Ambassador Nikki Haley  says Tehran gave to Yemenâs Houthi group.
 Haley  and  her  14 council colleagues will also lunch with President Donald Trump  the U.S. Mission to the United Nations said Friday.
The U.N. ambassadors will visit a military hangar at Joint Base Anacostia-Bolling near Washington  where  Haley   the U.S envoy to the United Nations  last month presented remnants of what the Pentagon said was an Iranian-made ballistic missile fired from Yemen on Nov. 4 at Saudi Arabiaâs capital Riyadh  as well as other weapons.
 Haley  said last month  she  was exploring several U.N. options for pressuring Iran to âadjust their behaviorâ. But  she  is likely to struggle to convince some Security Council members  like veto powers Russia and China  that U.N. action is needed.
 Haley  has said the Security Council could strengthen the provisions in that resolution or adopt a new resolution banning Iran from all activities related to ballistic missiles. To pass  a resolution needs nine votes in favor  and no vetoes by the United States  Britain  France  China or Russia.
Diplomats  speaking on condition of anonymity  say  Haley  has not signaled which accountability option  she  might pursue or when.

[EX Q]: Robert Dudley  who will replace Tony Hayward on Oct. 1  promised changes in light of the environmental disaster. "There's no question we are going to learn things from this investigation of the incident " he said.
 Hayward has some sympathy in his native Britain  where many pensions rely on BP stock and some consider U.S. outrage at the company to be over the top. A recurring theme in newspaper editorials and discussions among many Britons is that there simply wasn't much one man could do in the face of relentless American wrath.
 "BP sends Tony Hayward to Siberia to appease US " read a headline in the Guardian.
 Hayward  who will stay on BP's board until Nov. 30  will receive a year's salary of 1.045 million pounds (US$1.6 million) as part of his severance package. His pension benefits are valued at about 11 million pounds (US$16.8 million)  and he retains his rights to shares under a long-term performance program that could eventually be worth several million pounds if BP's share price recovers.
 Hayward said it was right that BP embark on its next phase under new leadership  and expressed his condolences for the families of the workers killed in the explosion.
 "The Gulf of Mexico explosion was a terrible tragedy for which -- as the man in charge of BP when it happened -- I will always feel a deep responsibility  regardless of where blame is ultimately found to lie " he said.
 President Barack Obama  who once said he would fire Hayward if he could  discussed the change in BP's leadership with Svanberg on Monday  Gibbs said Tuesday. No details about the conversation were released.
 Dudley spent some of his childhood in Mississippi and worked for 20 years at Amoco Corp.  which merged with BP in 1998. He lost out to Hayward on the CEO slot three years ago.
Hayward if he could  discussed the change in BP's leadership with Svanberg on Monday  Gibbs said Tuesday. No details about the conversation were released.
 "Our concern is not who heads BP " Gibbs said. "Mr. Hayward is leaving. The key is that BP can't leave and should not leave the Gulf. ... They have obligations and responsibilities as the responsible party in this instance that have to be met regardless of who the CEO is."

[EX Q]: In one of Patâs favorite interviews   Felipe CalderÃ³n  lectures Americans on how terrible states like Arizona are for cracking down on illegal immigration.
Several years ago   CalderÃ³n  sat down with Wolf Blitzer to discuss illegal immigration in his country and the U.S.âs âmistreatmentâ of illegal immigrants  and the most poignant point of all made by  CalderÃ³n  was when Blitzer asked  âIf somebody sneaks in from Nicaragua or some other country in Central America through the southern border of Mexico and they wind up in Mexico  they can go get a job? They can work?â
âIf somebody do that  without permissions  we send back them â said  CalderÃ³n .
 He  went on to share documentation is required by those entering into Mexico including some sort of assurance they arenât criminals.
What  CalderÃ³n  is saying here is the U.S. should allow everyone into this country and just let them be. âThat is just mindnumbing â said Pat. âAnd no awareness that thereâs any problem with it   he âs not even embarrassed to say it.â
