I am not defending this obvious buffoon, but those are ilima (the orange) and maile (the green) leis. Those are not tourist leis. Ilima leis, and maile leis to a lesser extent, are generally reserved for special/fancy events.
Having said that, it makes it worse to see him wearing such leis after this fustercluck. To me, who was born and raised in Hawaii, it shows a lack of humility. Like he's adorning himself after forgetting his Twitter password that left people there thinking they were about to die---What?!
Thanks for the info from a native Hawaiian. Kind of like the city folk who come to my area and dress in cowboy hat and boots who try to integrate with locals while proposing outrageous water rights deals.
