Tony Snow, the highly visible White House press secretary, will leave his job on Sept. 14 and be replaced by his deputy, Dana Perino, an administration official said Friday.
President Bush was to announce the changes during an appearance in the White House briefing room.
Snow, ailing with cancer, had said recently he would leave before the end of Bush's presidency because he needs to make more money.
The 52-year-old Snow was a conservative pundit and syndicated talk-show host on Fox News Radio before he was named press secretary on April 26, 2006. He is the latest in a string of White House officials to head for the exits.
