Just as the President was addressing reporters in the briefing room of the White House, a reminder of his departure arrived from the Kremlin, announcing that Russian leader Vladimir Putin has spoken by telephone with the President-Elect today.
One of the few issues where the President stressed his differences with Trump and other Republicans was on Mr. Obama's health reform law, which may prove tricky for the GOP to repeal.
"Do I have concerns? Absolutely, of course I've got concerns; he and I differ on a whole bunch of issues," the President said.
The President also weighed in a bit more strongly on immigration policy, saying the President-Elect should "think long and hard" about revoking the legal status of millions of people who were brought here illegally by their parents, known as "Dreamers."
"It is my strong belief that the majority of the American people would not want to see those kids hiding again," the President noted, though that has been the plan of his successor.
For the most part, though, Mr. Obama seemed to go out of his way to avoid direct challenges to his successor at this news conference.
"I think he's going to try - as best he can, to make sure that he delivers - not only for the people who voted for him, but for the people at large," Mr. Obama added.
"My hope is he makes things better, and if he does we'll all benefit from it."
