Obama continues Gulf visit, preps Oval Office address

(CNN) – President Obama will continue his Gulf Coast visit Tuesday with a stop in Florida's Panhandle, where beaches have started to see signs of oil as crude continues to gush from a ruptured deepwater well.

Obama, on his fourth trip to the region since oil began spewing from the well in April, is scheduled to return to Washington later Tuesday and address the nation about the situation from the Oval Office.

But first, Obama will give a speech of support for oil-impacted communities and American troops while at Pensacola's Naval Air Station Tuesday morning, an administration official said.

Meanwhile Rep. Ed Markey, D-Massachusetts, will have a chance to grill executives from five major oil companies on Capitol Hill.

The witness list for Tuesday's hearing of his House Energy and Environment subcommittee includes chief executives of BP, ExxonMobil, Chevron, ConocoPhillips and Shell Oil. Read more

Obama to address nation on oil disaster Tuesday night

(CNN) – President Barack Obama will visit the Gulf states affected by the oil spill on Monday and Tuesday and then address the nation on Tuesday night from the White House on the next steps in responding to the environmental catastrophe, his senior adviser said Sunday.

On his fourth visit to the Gulf region since the disaster began on April 20, Obama will make stops in Theodore, Alabama; Gulfport, Mississippi, and Pensacola, Florida, according to senior administration officials.

After returning from the two-day trip, Obama will make a televised statement from the Oval Office on the night before he is scheduled to meet with top BP officials.

David Axelrod, the senior adviser to Obama, said the president would push BP to create a BP-funded escrow account that will pay for damage claims from the worsening oil spill. In addition, Axelrod said, the plan would call for an independent third party to handle the claims process.

"The president will use every legal device at his disposal to make sure that this money is escrowed and that there is an independent administrator so that claims are not slow-walked, people can get the relief they need in a timely fashion and that we don't create more victims from this terrible disaster," Axelrod told reporters.

USGS: More oil gushing than believed

(CNN) – Scientists now estimate the leaking BP oil well in the Gulf of Mexico was releasing 20,000 to 40,000 barrels - or 840,000 to 1.7 million gallons - per day through last week, the head of the U.S. Geological Survey said Thursday.

The scientists' previous estimate was 12,000 to 19,000 barrels per day.

The new estimate is of the well's flow rate prior to BP's cutting of the damaged riser pipe extending from the well's blowout preventer last week, U.S. Geological Survey Director Marcia McNutt said. After BP cut the riser on June 3, it placed a containment cap over the preventer's lower marine riser package to capture some of the leaking oil.

Scientists estimate that the spill's flow rate increased by 4 to 5 percent after the well's riser pipe was cut last week in order to place the cap atop the well.

BP says that with the cap, it is capturing about 16,000 barrels daily and funneling it to a ship on the surface. Before that, BP was capturing some oil through a siphon inserted into the well riser. Read more

Exclusive: John Roberts tours BP's 'kill well' rig

(CNN) – We have seen the pictures from the ocean floor of the underwater volcano of oil erupting for 52 days now. But you may not know what's going on at the surface to stop this leak. It is incredible, unprecedented, very risky – and it has to work.

Our John Roberts saw the effort with his own eyes yesterday when he went out to ground zero, 40 miles off shore, with the man in charge of this effort, BP Chief Operating Officer for Exploration and Production Doug Suttles.

An army of oil workers, many who live along the coast they're working to save, are trying to hit something smaller than a basketball hoop five miles down and on the first shot. It's the closest BP has allowed anyone to get to their operations to kill the well. It's something you'll only see on American Morning.

Van der Sloot confesses to murder, Peruvian police say

(CNN) – Joran van der Sloot could be formally charged as early as Tuesday in the killing of Stephany Flores Ramirez, Peruvian government authorities said.

The government authorities said Van der Sloot confessed to murder late Monday. He will likely be held at one of three maximum security prisons - Castro Castro, Piedras Gordas and Lurigancho, authorities said.

Efforts by CNN to contact van der Sloot's attorney were not immediately successful.

At his first court appearance, the judge may set a hearing date for van der Sloot and could order additional investigations in the case. Read more

Obama seeks 'ass to kick' over spill

President Barack Obama bluntly defended his administration's response to the undersea gusher fouling the Gulf of Mexico on Monday, telling an interviewer he has met with experts to learn "whose ass to kick."

"I was down there a month ago, before most of these talking heads were even paying attention to the Gulf," Obama told NBC's "Today" show in an interview scheduled to air Tuesday. "A month ago I was meeting with fishermen down there, standing in the rain talking about what a potential crisis this could be." Read more

Can James Cameron help solve disaster?

James Cameron is an Oscar-winning director, but he also has decades of real-life experience as a deep sea explorer. Cameron has gathered a team of experts and government officials to come up with a solution in the Gulf. He's offering up his ideas to BP and the government to end the oil spill disaster, but are they listening? Our Jason Carroll spoke with Cameron and he'll join us this morning with his report.

Scientists say second oil plume lurking underwater

(CNN) – As if the pictures of birds, fish and animals killed by floating oil in the Gulf of Mexico is not disturbing enough, scientists now say they have found evidence of another danger lurking underwater.

The University of South Florida recently discovered a second oil plume in the northeastern gulf. The first plume was found by Mississippi universities in early May.

USF has concluded microscopic oil droplets are forming deep water oil plumes. After a weeklong analysis of water samples, USF scientists found more oil in deeper water.

"These hydrocarbons are from depth and not associated with sinking degraded oil but associated with the source of the Deep Horizon well head," said USF Chemical Oceanographer David Hollander.

Through isotopic or microscopic fingerprinting, Hollander and his USF crew were able to show the oil in the plume came from BP's blown out oil well. The surface oil's so-called fingerprint matched the tiny underwater droplet's fingerprint. Read more

Program note: It's an interview you don't want to miss this morning: She's a bona fide engineering prodigy.
