I really doubt that Trump would bring Obama to trial, but wouldn’t it be deliciously ironic to see Trump at the the podium announcing that, “For the good of the country, I’m extending clemency to former president Obama for his serious, serious crimes against the Constitution.”
Even better, ‘I’ve already had my lawyers build a pardon for my predecessor. I hope to execute that pardon by 2020, since legally I have to run it by my AG Jeff ‘Magoo’ Sessions first.’
‘In the meantime I would advise my predecessor against any further autobiographies’.
