Republican officials say Fox News commentator Tony Snow will be named White House press secretary today.
Snow was a speechwriter in the White House under President Bush's father.
He's written and spoken about the current president, and not always in a complimentary way.
Snow comes in to replace Scott McClellan, who is stepping down in a White House shakeup aimed at boosting President Bush's record-low approval ratings.
The liberal Center for American Progress is circulating unflattering observations by Snow about Bush.
Snow wrote last November after Republicans failed to win the governor's race in Virginia that "the newly passive George Bush has become something of an embarrassment."
Snow tells The Associated Press that as a columnist, he offers criticism and praise.
