World News Tonight Preview

Jan. 23 -- Good afternoon.

The top U.S. weapons inspector in Iraq is stepping down and he says weapons of mass destruction will never be found in Iraq. It was announced today that David Kay would be leaving the Iraq Survey Group, which has led the efforts to find banned weapons since the fall of Saddam Hussein's regime. With access to every classified document on the subject of Iraqi weapons and full knowledge of all of the search findings, Kay is believed to be the highest authority on the subject. Martha Raddatz reports tonight on Kay's comments and the reaction from the White House.

New Hampshire continues to be the battleground state for the Democratic presidential candidates as they enter the final weekend before the state's primary. Sen. John Kerry continues to lead in today's polls, though Howard Dean, Wesley Clark and John Edwards are still in the running. At last night's debate, the candidates avoided attacking each other and focused on gun regulation, the environment, the war in Iraq, and taking on President Bush this November. Bob Woodruff wraps up how each candidate fared in the debate and in today's campaigning. Barbara Pinto will also analyze the effect that Howard Dean's wife, Judith Steinberg, is having on his run for the nomination.http://abcnews.go.com/wire/Politics/reuters20040123_474.html

This week, soldiers with the 82nd Airborne Division are leaving Iraq to return to Fort Bragg, N.C. The unit has been in Iraq for 10 months and has seen a good deal of combat both during the war and after. But before heading home, they'll try to complete one final mission: the unit is now hunting the insurgents responsible for killing two of their comrades on Jan. 2. Ron Claiborne is in Iraq tonight, on the eve of the soldiers' homecoming.

And finally, we will reveal our Person of the Week.

We hope you'll join us.
