Obama today: 
“With respect to the transition, I think [the Trump team] would be the first to acknowledge that we have done everything we can to make sure that they are successful, as I promised, and that will continue,” the President said. 

He also noted that the DNC hack was widely reported months before the election.

Obama assured reporters that he took aggressive action to ensure other hacks wouldn’t affect Election Day. “In early September when I saw President Putin in China, I felt that the most effective way to ensure that that did not happen was to talk to him directly and tell him to cut it out…”

Rather than calling for more agitation, Obama recommended that Hillary voters accept their loss. “What I think is important for the Democratic Party is going forward, rather than try to parse every aspect of the election.”
