From NBC's Kelly O'Donnell
LENGTH: Advisers say the president's speech is running about 40 minutes. They also estimate that his walk to the podium takes 12 minutes, so with interruptions/applause and the speech itself, advisors guess at roughly an hour.
BRIEFING: Senior advisers will provide reporters with an on-the-record briefing which will be embargoed and reportable at speech time.
EXCERPTS: Excerpts of the president's address will be released at about 5:00 pm ET, with fact sheets early in the afternoon.
REHEARSALS: The president has continued to rehearse in the family theater at the White House. The speech has been revised more than 30 times, but every word change generates a new draft. Advisers say Bush has been involved in editing personally since very early drafts. About a half-dozen speechwriters have been working the text.
MAIN TOPICS: Advisers describe the address as centered on a "handful" of issues, as opposed to the usual, so-called laundry list of proposals. Advisers also say there's a focus on areas where the White House suggest both parties can work together. The topics will include Iraq, the greater war on terror, health care, energy, education, and immigration.
