Anna Sale, here, on the day shift.

President Obama addresses the nation tonight from the Oval Office. We're reaching back to some of the gulf residents we've talked to over the last two months, some of whom have met with Obama in the Gulf region over the last two days. We want to know how they rate Obama's speech. We're also watching Capitol Hill today, where executives from five oil companies are testifying. We also want to hear from you. Tell us what you hope to hear, and later tonight, share your reactions after tonight's speech. We'll be streaming the president's speech on our website. 

We're also following the United Auto Workers convention in Detroit. As the union celebrates its 75th anniversary, President Ron Gettelfinger is leaving his post after this convention; the union elects its new leader tomorrow. The transition comes after auto industry bailouts and major restructuring. We'll talk tomorrow about what the future of the UAW might look like.

And as the World Cup is making fans out of all of us (or the NBA finals, if that's more your speed), we're going to take a look at fans' brains. Psychologist Edward Hirt says "the agony and the ecstasy" is not all in your head, and true fans can feel real-life effects when their teams win or lose. He’ll be joined by superfan Nick Iwaniuk, who got the U.S. national soccer team’s crest tattooed on his chest.
