Leaders and members of two Hawaii labor unions gathered at Magic Island Wednesday during their lunch hour to announce their support for Kirk Caldwell.

The Hawaii Sheet Metal Workers and Ironworkers Local 625 Stabilization Fund thanked Honolulu’s mayor for helping to maintain infrastructure and jobs, identifying the impact of homelessness and unaffordable housing, and supporting rail — not coincidentally, the very platform that Caldwell is running on.

Caldwell, who shook the hand of all the laborers on hand, said he expected more labor backing as the campaign progresses. He told the unions that he would make sure there would be “rice in every rice bowl” if re-elected to another four years.

Wearing a new Sig Zane aloha shirt, the mayor also posed for a photo with a just-married Japanese couple.

“Isn’t it beautiful?” he asked them, referring to the park and ocean. “Having fun?”

Caldwell also asked that reporters only ask campaign-related questions, saying he’d prefer to take all other inquiries back at Honolulu Hale.

The two unions join the Hawaii Construction Alliance, which announced its endorsement of Caldwell last week.

The alliance represents the Hawaii Regional Council of Carpenters, the Operative Plasterers’ and Cement Masons’ International Association, Local 630; the International Union of Bricklayers & Allied Craftworkers, Local 1; the Laborers’ International Union of North America, Local 368; and the Operating Engineers, Local Union No. 3.

Caldwell’s declared opponents (so far) include former Mayor Peter Carlisle and several other candidates who have filed papers to run.
