U.S. President Barack Obamathanked his supporters at an inaugural reception at the National Building Museum in Washington ahead of the public ceremony.
The President was joined on stage by First Lady Michelle Obama, Vice President Joe Biden and Dr. Jill Biden.
Obama, who kept his remarks brief, said the inauguration on Monday (January 21) was a very important celebration.
"Make sure you know what we are celebrating is not the election or swearing-in of a President; what we are doing is celebrating each other and celebrating this incredible nation that we call home. And after we celebrate, let's make sure to work as hard as we can to pass on an America that is worthy not only of our past but also of our future," he said.
