I was wondering what document do I need to check myself in if I'm going to Hawaii from Portland Oregon?? Ever since the new law came in. I don't know what documents I need anymore beside my ID...

ALL OF THEM. THE MORE YOU HAVE THE BETTER.

According to the TSA your Oregon drivers licence will do.

All you need is your Identification card i.e driver's license the only time you need more than that is if you were flying OUT OF USA territory and example China Japan Mexico London so on and so forth but not from Hawaii to pdx I've done that flight 8 times 2 of those within the last yr

Just your passport if your a citizen
