I didn't cite it because this thread is about Obama not the DNC
And what should have he done? Trump was already bitching about a 'rigged system' and tacitly threatening to contest the election had he lost. Do you think that if President Obama had done more than shut down,the Russian compounds and expelled a few Russian operative the election would have gone on without further turmoil?
Had Trump acted like a responsible grownup and not started bitching and complaining before the fact (good luck with that) perhaps more reasonable and responsible actions could have occurred. As it was, anything President Obama would have said or did would just serve to muddy up already fetid waters.
