Honolulu Mayor Mufi Hannemann formally kicked off his re-election campaign today by filing nominating papers at the office of the city clerk.

Flanked by family members and supporters, Hannemann signed the papers and submitted them at Honolulu Hale shortly after noon today.

After filing he walked out to greet more than three dozen supporters who were waving campaign signs and chanting "four more years."

Hannemann thanked his family, friends, campaign staff and city workers who attended the "chill with Mufi" event, that featured ice cream and cookies.

"No one will work harder, no one will work smarter and no one will work with more aloha than the individual standing before you," said Hannemann.
