Portions of Arizona's controversial immigration law go into effect

(CNN) – Parts of an Arizona immigration law go into effect Thursday as it was passed - after a federal judge granted a preliminary injunction that blocked the most controversial aspects of it.

The injunction, issued Wednesday, means that, at least for now, police are prevented from questioning people's immigration status if there is reason to believe they are in the country illegally.

U.S. District Judge Susan Bolton also blocked provisions of the law making it a crime to fail to apply for or carry alien registration papers or "for an unauthorized alien to solicit, apply for, or perform work," and a provision "authorizing the warrantless arrest of a person" if there is reason to believe that person might be subject to deportation.

Arizona Gov. Jan Brewer said the state would file an expedited appeal to the 9th Circuit Court of Appeals, signaling a legal escalation that some expect will end up before the U.S. Supreme Court.

The parts of the law that go into effect include a ban on so-called sanctuary cities, and the criminalization of hiring day laborers who are in the country illegally. The parts of the law dealing with sanctions for employers who hire illegal immigrants also withstood the first legal test. Read more

100 days later, devastation and hope as oil spill efforts take hold

(CNN) – An oil well ruptured in the Gulf of Mexico 100 days ago, setting into motion the worst environment disaster in U.S. history.

The toll to the region has been crushing as millions of barrels of oil spewed from a mile below the surface.

On Wednesday, 100 days on, thousands of workers have lost their jobs, sensitive wetlands have been damaged and tourism is at a near standstill.

But efforts to contain the underwater gusher appear to be taking hold.

Coast Guard Rear Adm. Paul Zukunft, the federal on-scene commander for cleanup, said a fleet of 800 skimmers collected only one barrel of oil Monday. A containment cap put in place nearly two weeks ago appears to be up to the task.

At the height of the spill, they were collecting 25,000 barrels of oil a day.

"The task that's laid out before us is very clear right now," said retired Coast Guard Adm. Thad Allen, the man in charge of the federal Gulf of Mexico oil crisis response said Tuesday.

"We have absolute priorities on killing the well, maintaining the recovery, making sure the oil is all removed and making sure the beaches are cleaned up and that the commitment by BP to the people is met," he said.

Crews are back on track to permanently shut down BP's once-gushing wellhead in the next few weeks, if setbacks are avoided and weather permits. Read more

BP ousts CEO Hayward and taps an American

(CNNMoney) – Tony Hayward will step down as chief executive of BP, the company announced Tuesday, amid ongoing outrage over the oil spill in the Gulf of Mexico.

BP said Hayward will be replaced by American Robert Dudley effective Oct. 1.

Like Hayward, Dudley is a long-time BP employee with more than 30 years in the oil business. A chemical engineer by training, Dudley was put in charge of the day-to-day leadership of the Gulf Coast clean-up operation in June.

BP said Hayward will receive a year's salary amounting to $1.6 million but further details of his severance package were not disclosed.

The company also plans to nominate him as a non-executive director of Russian oil and gas venture TNK-BP.

The announcement of the change in leadership came as BP reported a second-quarter net loss of $17.2 billion. The heavy loss was due to a $32.2 billion charge the company took related to the oil disaster.

The news ends weeks of speculation about management changes at the company responsible for what has been called the worst environmental disaster in U.S. history. It also presents an opportunity for BP to put a new public face on the company as it seeks to rebuild its reputation. Read more

BP says no decisions have been made on changing management

(CNN) – No final decision had been made regarding whether embattled CEO Tony Haward will leave BP, the company said in a statement Monday morning.

"BP notes the press speculation over the weekend regarding potential changes to management and the charge for the costs of the Gulf of Mexico oil spill. BP confirms that no final decision has been made on these matters," the statement said.

The statement, which did not mention Hayward by name, said "any decisions will be announced as appropriate," noting that BP's board would meet Monday night ahead of the announcement of its second quarter earnings.

Despite widespread media reports that Hayward was on the verge of leaving, BP said Sunday that he still had the company's support.

"Tony Hayward remains our chief executive and has the full support of the board and senior management," company spokesman Mark Salt told CNN.

Hayward has been in the crosshairs of criticism over his handling of the underwater oil gusher in the Gulf of Mexico ever since the BP-contracted Deepwater Horizon drilling rig exploded in April, killing 11 people and creating the worst oil spill in U.S. history. Read more

Tropical Storm Bonnie could hit oil spill site over weekend

(CNN) – The National Hurricane Center issued a tropical storm watch for the northern Gulf of Mexico early Friday as Tropical Storm Bonnie began clearing the Bahamas and headed for South Florida.

The watch is in place from Destin, Florida, westward to Morgan City, Louisiana.

The storm is expected to pass the southern tip of Florida on Friday afternoon before making landfall Sunday morning near New Orleans.

At 5 a.m. ET Friday, Bonnie was packing winds of 40 mph and moving west-northwest at 18 miles an hour as it slipped past the northwestern Bahamas. It was about 200 miles east-southeast of Key West, Florida, according to the National Hurricane Center.

It could pick up some strength as it moves over the long stretch of open water in the Gulf of Mexico, but the latest computer models do not show it becoming a hurricane, according to CNN meteorologist Chad Myers.

If the storm continues on its path, it could slam into the area of the BP oil spill and possibly put more oil to shore. Read more
