From a Mike McGavick for Senate email:

SEATTLE—Mike McGavick's U.S. Senate campaign announced today that former New York City Mayor Rudy Giuliani will visit Seattle in October to campaign and fundraise for Mike. 

"I'm incredibly honored to have the support of Mayor Giuliani," Mike said. "Mayor Giuliani will always be remembered as a great American leader, an outstanding mayor, and someone whose decisive, clear-headed leadership helped guide this country through the tragic aftermath of 9/11. He has never been afraid to be an independent thinker and exemplifies what it means to put our citizens first. I look forward to him joining me in Washington state," Mike said.
