That's assuming that Oregon can come up with the money that is expiring per Obamacare's terms.  

Oregon agreed to take the 'extra' Medicaid money knowing full well that the extra Federal money was scheduled to disappear at the end of Obama's term.

That missing money is part of the $1.2 billion 'shortfall' here in Oregon.

Now Oregon taxpayers have to replace that money.  And that has nothing to do with Trump at all. Pelosi and Reid designed the ACA Bill that way.
