Palin omitted from White House Iraq troop briefing
"We are keeping them informed about activities and remember, certainly, they have committee assignments and things like that as senators as well," White House press secretary Dana Perino said Friday. "One of them is going to win the election, and they will be taking over and having to deal with these issues ... So it's only prudent for us to make sure that we get them the information that we think they need."
John McCain got a call from Defense Secretary Robert Gates. Secretary of State Condoleezza Rice was on the phone to Barack Obama, and to his Democratic running mate, Joe Biden. Nobody called Sarah Palin.
