“What he has to appreciate is as soon as you walk into this office after you've been sworn in, you're now in charge of the largest organisation on Earth,” Obama said.
Obama further made Trump know the operation can't be managed like a family business, and he will have to have a strong team around him.
“You have to have respect for institutions and the process to make good decisions because you are inherently reliant on other folks,” Obama adds.
On the same note, Obama interview comes as he prepares for a farewell address scheduled to take place Tuesday evening and as he prepares to leave office on January 20, the same day Trump will be inaugurated.
Obama added that he has also talked to Trump about having confidence in U.S. intelligence agencies and knowing that “there are going to be times where the only way you can make a good decision is if you have confidence that the process is working.”
Top US intelligence officials on Friday briefed Trump about their investigation into Russian cyber activities during the presidential election.
The president in an interview with ABC, also said he had given Trump advice about using Twitter.
He said from the day Trump becomes president “there are world capitals and financial markets and people all around the world who take really seriously what he says.”
