CNN has obtained the letter Barack Obama left for Donald Trump on Inauguration Day in January. Obama congratulated Trump on his "remarkable run" and then offered four pieces of advice.
- Recognize that they've been fortunate, and "build ladders of success" for others.
- Appreciate that the wealth and safety of much of the world depends on American leadership.
- Guard institutions like the rule of law and civil liberties and leave them "at least as strong as we found them."
- Make time for friends and family.
