OBAMA HAS MADE HIS VEEP PICK

Barack Obama said Thursday that he has decided on his running mate. And that's all you're going to get.

Intent on extending the drama as long as possible, the unofficial Democratic presidential nominee would go no further. Nothing on whether his intended has been notified, or the also-rans let down easy. Nothing about when the union might be made official -- although the plan was still that news would be text-messaged to Obama supporters soon, and perhaps unveiled in the flesh at a Saturday extravaganza in Springfield, Ill., where Obama's campaign began.

THREATS SENT TO MCCAIN OFFICES

Threatening letters were sent to John McCain campaign offices in Colorado and New Hampshire on Thursday, officials said. The Colorado letter contained small amounts of an unidentified white powder.

No injuries were immediately reported at the Colorado site. At least 19 people were examined at hospitals or were quarantined outside the office in Centennial, Colo., a Denver suburb.

The official said authorities believe the Denver letter was a hoax because it appeared to have been sent from a jail. The official spoke on condition of anonymity because nothing will be certain until the powder is tested.

Andy Lyon of Parker South Metro Fire Rescue Authority said firefighters found very little powder when they arrived. "There were maybe a couple of grains of something inside an envelope and they had to kind of work to get a sample," he said.

FALL DEBATE SCHEDULE IS SET

John McCain and Barack Obama have agreed to hold three presidential debates and one vice presidential debate this fall. They are:

• Sept. 26 at the University of Mississippi, with moderator Jim Lehrer.

• Oct. 7 at Belmont University, with moderator Tom Brokaw.

• Oct. 15 at Hofstra University, with moderator Bob Schieffer.

Vice presidential contenders will meet Oct. 2 at Washington University in St. Louis.
