Although President Obama is probably associated with the state of Hawai'i more than any other politician now, just the other day I was reminded of former President Clinton's 1993 "Apology Resolution."
This joint resolution basically acknowledges and of course apologizes for America's role in the overthrow of the Queen Liliuokalani's monarchy on January 17, 1893.
The joint resolution was extremely welcomed by many politicians and locals alike, but also stirred a lot of controversy when it was adopted. It continues to have a place in judicial discourse as recently as 2009, when the Supreme Court responded to the Hawaiian Sovereignty Movement by in essence affirming that the resolution had no legal effect on Hawaii's status as a US state.
I was unaware that apparently every year Hawai'i sovereignty activists gather at the Iolani Palace grounds to voice their desire for more independence from the US.
