Afghanistan decision

By Lester Holt, NBC News anchor

The White House is reacting to a new development in Afghanistan today that could affect how and when it decides whether to commit more American troops to the war. President Hamid Karzai's election rival, Abdullah Abdullah, is now expected to drop out of a runoff election as soon as tomorrow.

Whether he does it gracefully, or in effect boycotts what he has previously labeled a fraudulent election process, is the burning question. Clearly Washington would like to remove any stain of illegitimacy from the election before deepening American involvement in the conflict. Our Richard Engel is in Kabul and will bring us the latest from there. We'll also get the early reaction from the White House.

We're also covering an unsettling discovery at the home of a convicted rapist in Cleveland.

That case of a Northwest Airlines crew who overflew their destination last week has stirred up discussion about fatigue in the cockpit. Ron Allen looks into the problem.

And by the way, for those of you who watched TODAY this morning, I can promise there will be no encore tonight to our little Halloween musical (ok, lip-syncing) performance. It will be suit and tie the whole way this evening. I hope you'll join me for Nightly News, and in the meantime have a safe and enjoyable Halloween night.
