President Barack Obama has just one day left in the White House – and he has used his time to write a very important letter to the people of America.

The powerful message, which has been shared on the official White House blog, begins with Obama confirming that he has chosen to add his own unique twist to a long-standing presidential tradition; as well as leaving a letter for his successor, Donald Trump, he has chosen to share one with the citizens of the USA, too.

“It's a long-standing tradition for the sitting president of the United States to leave a parting letter in the Oval Office for the American elected to take his or her place,” he explains. “It's a letter meant to share what we know, what we've learned, and what small wisdom may help our successor bear the great responsibility that comes with the highest office in our land, and the leadership of the free world.

“But before I leave my note for our 45th president, I wanted to say one final thank you for the honour of serving as your 44th. Because all that I've learned in my time in office, I've learned from you.”
