After days of rumors and speculation, much of it fed by himself, Tony Snow’s run as a Fox News commentator and radio show host ended with his appointment Wednesday by President Bush as White House press secretary.

A Fox News statement issued Wednesday said: “We’re proud of the work Tony did for Fox as a commentator and we wish him all the best in his second stint at the White House.”

Mr. Snow, who was hired in 1996 to moderate “Fox News Sunday,” served as a speechwriter for President George H.W. Bush. He replaces Scott McClellan.
