It's what happens from now will be interesting.
I liked Obama's tone in that interview, he knows the idea of Trump not getting the presidency at this stage is virtually impossible so he's shifted the onus onto Trump himself. I think he knows he's been compromised and he's leaning on him to take a stand against Putin and Russia - something I think he won't be able to do out of either sheer pigheadedness or because he has indeed been compromised.
He's made sure a huge spotlight is on Trump's link to Russia and he's asked American's if they're OK with having their President under the Thumb of a historical (and hugely dangerous) rival.
