It's everywhere. US News and World Report has the story:
Sparked by today's Washington Post story that suggests Vice President Cheney's office is involved in the Plame-CIA spy link investigation, government officials and advisers passed around rumors that the vice president might step aside and that President Bush would elevate Secretary of State Condoleezza Rice.
Said another Bush associate of the rumor, "Yes. This is not good." The rumor spread so fast that some Republicans by late morning were already drawing up reasons why Rice couldn't get the job or run for president in 2008.
