Arwa Gunja here on the night shift.

Tomorrow, we’re going to try to answer some looming questions over the big stories of the day.

First, to the Natalee Holloway case. The AP reported this week that Joran van der Sloot, the prime suspect in Holloway’s disappearance, was paid $15,000 by the FBI in a sting operation. Van der Sloot used the money to flee from Aruba to Peru where he is suspected of killing another young woman. So the question is, why did the FBI give van der Sloot money instead of arresting him when they had the chance? Tomorrow, Craig Dotlo, a former FBI agent will join the program to help explain the organization’s actions and the inner workings of the FBI when it comes to cases like this.

Next to the oil spill. There seems to be a lot of outrage, but not a lot of action, and many Americans, especially those along the Gulf Coast, want to know why there isn’t more of a push on Capitol Hill to stop offshore drilling. What are environmental groups doing? How about politicians and business leaders? Ted Nordhaus is the chairman of The Breakthrough Institute, and he’ll explain why environment groups aren’t being more vocal about ending offshore drilling. And Louise Story, finance and Wall Street reporter for our partner The New York Times, says a group of prominent business leaders actually have been outspoken and are urging Congress to triple its budget for investments in alternative energies.

And as always we want to hear from you. The World Cup officially kicks off this weekend. Tell us how you’ll be watching, what teams you’re rooting for and your predictions over the next month. Call our comment line at 877-8-MYTAKE or leave us a message here on our website.

Anna Sale here on the day shift.

Get ready. We've been building up to it all week, and tomorrow, while we're on the air, we'll listen in on the opening ceremonies of the World Cup. Players take the field just a few hours later, and we'll listen in as fans gather in bars for the first game of the home team, as South Africa takes on Mexico. We'll also give you a viewing guide for the first U.S. match against England, and we'll hear from a player on the 1950 U.S. National Team. We're also looking for you to help us cover this story. Who are you rooting for and why? How do you celebrate the teams? Special foods? Special rituals? Share your World Cup stories with us.

We will also mark the one year anniversary of the post-election protests in Iran. Next week, HBO will broadcast a new documentary called "For Neda," which features exclusive interviews and never-before-seen footage of Neda Agha-Soltan, whose iconic death went viral last year during those protests. We'll hear from filmmakers Antony Thomas and Saeed Kamali Dehghan, who got exclusive interviews with her family, and footage of Neda’s life and death. Saeed worked secretly in Iran — and can no longer return there. We'll also be joined by journalist Stephen Kinzer, author of "All the Shah's Men."

Finally, Joan Rivers stopped by this week to talk with our Movie Date podcast team, Kristen Meinzer and Rafer Guzman, about the new documentary on her life, aptly called "A Piece of Work." Directed by Ricki Stern, the film follows Rivers over the course of 14 months — from the opening of her newest play in London to her triumphant win on "Celebrity Apprentice.' There's nothing like Rivers' biting humor, even when she's reflecting on her life's most painful moments. You've got to hear this.
