Actually, Ryan you are correct! Those were donated by OHA.

"While opposition to the TMT was on the minds of many marchers, the free T-shirts distributed by OHA at the event were construed by some as pushing another controversial cause."

"The shirts featured a triangle symbol that is also featured on a website for Nai Aupuni, a recently formed organization that is guiding efforts for an election and convention for Native Hawaiians that could lead to a degree of governmental self-determination."

"Civil Beat found no evidence linking the 'kakou' T-shirts with Nai Aupuni. In his memo, Crabbe says nothing about Nai Aupuni or elections."

I still think CivilBeat could have found a better picture to use that is more representative of those actually seeking federal recognition, instead of those that came together to oppose the TMT.
