GULF OF MEXICO - Tuesday, May 18, marked day 29 of a Gulf of Mexico oil spill that began with an explosion and fire April 20 on the drilling rig Deepwater Horizon, owned by Transocean Ltd. and leased by BP PLC, which is in charge of cleanup and containment.

The blast killed 11 workers. Since then, oil has been pouring into the Gulf from a blown-out undersea well at a rate of at least 210,000 gallons per day. Here is the latest information in the situation.

Inquiries on Offshore Drilling

Interior Secretary Ken Salazar concedes the government failed to hold the oil industry accountable and ensure safety in offshore oil drilling. He promises to give "more tools, more resources, more independence and greater authority" to the Minerals Management Service, which regulates drilling in the Gulf of Mexico.

Salazar on Tuesday was making his first appearance before Congress since the explosion. Two Senate committees held hearings Tuesday. Environmental Protection Agency Administrator Lisa Jackson and Coast Guard Commandant Thad Allen were also testifying.

Collection the Oil From the Blown-out Well

 BP says its mile-long tube siphoning oil from a blown-out well is bringing more crude to the surface. In a news release Tuesday, BP PLC says the narrow tube is now drawing 84,000 gallons a day for collection in a tanker - double the amount drawn when it started operation Sunday.

BP -- which puts the leak at 210,000 gallons -- has said it hopes to draw about half the leaking oil. Scientists who have studied video of the leak say the amount could be significantly more.

19% of Fishing Closed Down in Gulf

 Federal officials say they're expanding the area of the Gulf of Mexico where fishing is shut down. They had already shut down fishing from the Mississippi River to the Florida Panhandle, about 7 percent of federal waters were affected.

Now, nearly 46,000 square miles, or about 19 percent of federal waters, will be shut under the expanded ban.

Where is it Going?

Government scientists are surveying the Gulf of Mexico to determine if oil from the spill has entered a powerful current that could take it to Florida. National Oceanic and Atmospheric Administration Administrator Jane Lubchenco says aerial surveys show some tendrils of light oil close to or already in the loop current, which circulates in the Gulf and takes water south to the Florida Keys and the Gulf Stream.

But most oil is dozens of miles away from the current. Lubchenco says it will take about eight to 10 days after oil enters the current before it begins to reach Florida. But scientists from the University of South Florida are forecasting it could reach Key West by Sunday.

Native Americans and the Oil Spill

Like many American Indians on the bayou, Emary Billiot blames oil companies for ruining his ancestral marsh over the decades. Still, he's always been able to fish - but now even that is not a certainty.

The oil spill has closed bays and lakes in Louisiana's bountiful delta, including fishing grounds that feed the last American-Indian villages in three parishes. It is a bitter blow for the tribes of south Louisiana, who charge that drilling has already destroyed their swamps and that oil and land companies illegally grabbed vast areas.
