Why does Trimet say they are getting $35-40 million from the state while the state says its $71 million

The answer is simple and its standard operating tactic at Trimet. 
They are low-balling and holding money back from the public. 
They've done this before

I found one of them, says right here $71 million a yearhttps://t.co/0GVkEGhidX pic.twitter.com/I7rKXy9jLF
