Immigration reform: It's another issue that divides Americans. Just what should the U.S. government do with immigrants who are in the country illegally?  Next week we'll take an in-depth look at the topic as the Senate considers a controversial bill, but we'll begin our coverage tonight with a report from NBC's Mark Mullen in our Burbank bureau.  He'll tell you why thousands of people in Los Angeles, Phoenix and Atlanta staged school walkouts, marches and other work stoppages today.

Among the other stories you won't want to miss tonight:

"THE WAR IN IRAQ: 3 YEARS LATER": Tonight, we conclude our anniversary coverage with a remarkable retrospective from our man in Baghdad, Richard Engel. Richard's been in Iraq from the beginning, before the first bombs fell. He's seen it all, and as you'll see tonight, recorded a lot of it in his personal video diary.

We'll also focus tonight on the shifting opinion of the war here at home.  NBC's Mike Taibbi reports from Susquehanna High School in rural Pennsylvania, where students continue to enlist even as some residents begin to raise doubts about what the U.S. is doing in Iraq. 

If you missed any of this week's series, you can find all the stories and video at www.Nightly.MSNBC.com.

MAKING A DIFFERENCE: NBC's Anne Thompson brings you the story of a pink dress and how it kept one high school prom in Ocean Springs, Miss., from becoming another casualty of Katrina.

We hope you'll join us for those stories and all the rest of the day's news.
