Barack Obama will deliver his final speech as US President later today in his adopted hometown of Chicago.
In ten days, President-elect Donald Trump will swear the oath of office and become the 45th President of the United States.
Confirmation hearings for his cabinet nominees begin on Capitol Hill later today.
Several thousand people are expected to attend the free, ticketed event at Chicago's McCormick Place, a lakefront convention centre where Mr Obama will deliver his speech.
He has been working with White House speechwriters on the piece since mid-December which senior advisors say is "not a victory lap speech", but will offer thoughts on where the US goes next.
Mr Obama says he will also thank supporters and mark his achievements.
His wife Michelle Obama and Vice President Joe Biden will also attend.
Later, the first hearings to confirm Mr Trump's cabinet nominees will begin on Capitol Hill, starting with Alabama Senator Jeff Sessions, who the president-elect has tapped for Attorney General.
Although he later worked on some equality cases, Mr Sessions was refused a judgeship in Alabama in the 1980s following allegations of racism.
Congressman and civil rights icon John Lewis and Senator Cory Booker, both African American Democrats, will testify against Mr Sessions' appointment.
General John Kelly, tipped to be Homeland Security Secretary, will also appear before a Senate Committee, while another hearing will get under way to consider a waiver allowing retired general James "Mad Dog" Mattis to become Defence Secretary although he has not been retired from the military for the required seven-year period.
Mr Trump has also named his son-in-law Jared Kushner as Senior Adviser.
He will not receive a salary while in the White House.
