USA Today's 'On Politics' blog reports: Barack Obama told USA TODAY this afternoon that "yes," he has made up his mind about whom his running mate will be -- but he would not reveal the name or just when he will tell the nation about his choice. USA TODAY's Kathy Kiely writes that:
In an interview in Chester, Va., the presumptive Democratic presidential nominee said he's made up his mind, but he would not say whether he's informed that person yet. "I won't comment on anything else until I introduce our running mate to the world," he said. "That's all you're going to get out of me."
Obama said it was a difficult decision. "We had some great choices."
Obama said he wanted somebody who is "prepared to be president" and who will be "a partner with me in strengthening this economy for the middle class and working families."
He said he was looking for not just a partner but a sparring partner. "I want somebody who's independent, somebody who can push against my preconceived notions and challenge me so we have got a robust debate in the White House."
Here's a very brief audio clip of the exchange Kathy had with Obama about whether he's made up his mind.
The full story will be available later today.
