Adviser: Palin to give 'meaty' speech

From NBC's Norah O'Donnell
TUCSON, AZ -- A senior McCain adviser says Sarah Palin will deliver a "meaty" speech -- the bulk of which is about the Arizona senator -- at today's McCain-Palin rally here. 

The adviser estimates the event will start at 3:15 pm ET. Cindy McCain will intro Palin, and Palin will speak about 10-12 minutes, while John McCain will speak for about five minutes.
