The massive oil slick in the Gulf of Mexico is about to come ashore and five-times bigger than first thought. Louisiana is on alert with the 120-mile sick advancing to its shores and expected to hit land within the next few hours.
Louisiana Gov. Bobby Jindal has declared a state of emergency. That's not all. Homeland Security Secretary Janet Napolitano declared the spill a crisis of "national significance" - a move that allows the government to use resources from across the country to battle the spill. Napolitano and two other cabinet secretaries will travel to the Gulf coast tomorrow to get a first-hand look at the spill.
The focus tonight is doing everything to lessen the environmental impact. The oil could kill or sicken fish, birds and other animals. About 33 miles of floating booms have been deployed in the area.
The latest forecast from NOAA shows the slick reaching Mississippi and Alabama over the weekend and going as far as Pensacola, Florida, by Monday.
Efforts to stop the oil leak have failed and it could take weeks or even months to shut it down. Just last night they discovered a third leak pushing five times as much oil into the Gulf as first estimated - about 5,000 barrels or 210,000 gallons a day.
We'll give you an up close look at the huge challenges ahead. We'll also dig deeper on the controversy over offshore drilling.
Also tonight, singer Shakira talks about why she's boycotting the state of Arizona over its immigration law. There are so new battle lines being drawn over the legislation.
We'll also give you an exclusive look at the first clinical trial using fetal stell cells that are injected in a patient with ALS or better knowns as Lou Gehrig's disease. Could it be a medical breakthrough? Dr. Sanjay Gupta has the story.
Join us for all this and much more at 10 p.m. ET. See you then.

A police officer in Tucson, Arizona, filed a lawsuit against the state's governor Thursday over a new immigration law.
Officer Martin H. Escobar says in the lawsuit that there are no "race-neutral criteria or basis to suspect or identify who is lawfully in the United States."

A 120-mile oil slick advanced to within a few miles of the mouth of the Mississippi River on Thursday as authorities scrambled to keep the spill from damaging sensitive coastal wetlands along the Gulf of Mexico.
As of late Thursday morning, southeasterly winds had driven the slick to about three miles off the Louisiana coast, National Oceanographic and Atmospheric Administration spokesman Charlie Henry told reporters.
Louisiana Gov. Bobby Jindal declared a state of emergency Thursday as authorities scrambled to mitigate its environmental effects.

Program Note: Watch Randi's full report tonight on AC360° at 10 p.m. ET.
We are on our way to cover the story of the Arizona rancher police say was killed by illegal immigrants, drug smugglers who Sheriff Larry Dever says crossed the US/Mexico border illegally and worked their way through the San Bernardino Wildlife Refuge, which is federal land. The victim in this case, cattle rancher Rob Krentz, owned 35,000 acres of land that butted up to that wildlife refuge.
His ranch is in the middle of nowhere. We flew 6 hours to get to Arizona and then drove another 3 hours or so to the tiny (supposedly haunted) town of Bisbee, AZ.

Editor's Note: Pop star Shakira talks about why she's fighting Arizona's immigration law on "AC360" tonight at 10 ET on CNN.
It's the week before finals at the University of Arizona in Tucson, and all over campus, students are hunched over books and laptops under the shelter of immense palm trees and sprawled out on the cement benches lining the campus' long, grassy mall, the anticipation palpable.
Elsewhere, in the Cesar Chavez Building, graduate student Francisco Baires sits in a windowless office that could have been a closet in a previous life, immersed in a different kind of work: He is sending a statement condemning Arizona's new anti-illegal immigration law to the media and other opponents of Senate Bill 1070.
The National Institutes of Health
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
The ALS Association
Amyotrophic lateral sclerosis (ALS), often referred to as "Lou Gehrig's Disease," is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.
With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.
Our patient, an adult male, was in the throes of a severe asthma attack. Standing at his head, I gripped the laryngoscope in my left hand and paused. I had watched doctors deftly insert metal devices just like this one into patients' mouths many times before - they had made it look so easy. But now I was holding the instrument that resembled a socket wrench with a flat blade - and the patient was crashing.
"Doc, I don't feel so good." Just minutes earlier, those had been his first words as we surrounded his gurney. Pressing a stethoscope to his chest, I had listened to the unmistakable wheezing sounds of an asthma attack. The monitor nearby showed his heart was beating far too fast. Someone on the team administered oxygen, but within moments his condition went from bad to worse. His blood oxygen levels were plunging, his lips had turned blue.
That's when the attending handed me the laryngoscope, calmly explaining we needed to intubate our struggling patient. Translation: insert a flexible plastic tube into his trachea so we could breathe for him; the laryngoscope would help me see where to put the tube. In medical dramas like ER and Grey’s Anatomy, this is when they yell, "Bag him!"
