In a “parting letter” to the American people, President Obama on Thursday reflected on his time in office, thanked his supporters and offered a way to keep in touch.

“[B]efore I leave my note for our 45th president, I wanted to say one final thank you for the honor of serving as your 44th,” he began. "Because all that I've learned in my time in office, I've learned from you. You made me a better President, and you made me a better man.”

"I've seen neighbors and communities take care of each other during the worst economic crisis of our lifetimes. I have mourned with grieving families searching for answers — and found grace in a Charleston church,” Obama wrote on his Facebook page on his final day in office.
