WASHINGTON (CNN) - Sen. Sam Brownback of Kansas told CNN he is "stunned" by the news that Arlen Specter is switching parties.
Walking into emergency meeting of GOP Senators, Brownback stopped to read his BlackBerry and his mouth dropped.
"Arlen's his own man, but it's not good," he said.
"I'm just stunned, just heard about it here," Brownback said, motioning to his BlackBerry. "I'm very surprised. I had no idea it was coming."
