US President Donald Trump says he took a “beautiful” letter from former President Barack Obama, which he will keep secret.
Addressing senior staff members on Sunday, Trump said that he "just went to the Oval Office and found this beautiful letter from President Obama."
"It was really very nice of him to do that and we will cherish that. We will keep that and we won't even tell the press what's in that letter."
Outgoing presidents leave a letter in the Oval Office for the new leader.
In the letter Obama himself received, former President George W. Bush reminded him of "trying moments," when "critics will rage" and "'friends' will disappoint you."
"But, you will have an Almighty God to comfort you, a family who loves you, and a country that is pulling for you, including me," Bush wrote. "No matter what comes, you will be inspired by the character and compassion of the people you now lead."
Former President Bill Clinton had also wished Bush "success and much happiness," adding that, "the burdens you now shoulder are great but often exaggerated. The sheer joy of doing what you believe is right is inexpressible.”
Trump was sworn in during an inauguration ceremony on Friday to become the 45th US president.
His term begins as massive protests are held against some of his policies, including a complete ban on Muslims to enter the United States, building a wall to stop refugees at the Mexican border, and moving the US embassy in Israel from Tel Aviv East Jerusalem al-Quds.
