Donald Trump will say he will "pray for the success" of Joe Biden's administration in his farewell address later but that the political movement he created "is only just beginning".
Before he leaves office tomorrow, the outgoing president said everyone in the US had been "horrified" by the rioting at the Capitol in Washington DC earlier this month.
In extracts released by the White House, he said: "Political violence is an attack on everything we cherish as Americans. It can never be tolerated."
He added: "As I prepare to hand power over to a new administration at noon on Wednesday, I want you to know that the movement we started is only just beginning."

Mr Trump also said he would pray for the success of the new administration in keeping America safe and prosperous, but he did not mention Joe Biden by name.
He went on: "Our agenda was not about right or left, it wasn't about Republican or Democrat, but about the good of a nation, and that means the whole nation."
He said his administration had "restored American strength at home - and American leadership abroad", and it "built the greatest economy in the history of the world".
Under his leadership, Mr Trump claimed the US had "revitalised our alliances and rallied the nations of the world to stand up to China like never before".
And he said: "As a result of our bold diplomacy and principled realism, we achieved a series of historic peace deals in the Middle East. It is the dawn of a new Middle East and we are bringing our soldiers home."
He also said he was "especially proud" to be the first president in decades who has "started no new wars".
Mr Trump will not attend tomorrow's inauguration - the first outgoing president to skip the ceremony since Andrew Johnson more than a century and a half ago.
Before leaving Delaware for Washington DC, Mr Biden addressed dozens of supporters in an emotional sendoff in the state where he was a senator for decades.
As the US exceeded 400,000 coronavirus deaths, the president-elect said: "These are dark times. But there's always light."
The president-elect flew to Joint Base Andrews in Maryland on a chartered plane.
This was in contrast to his predecessor, who arrived at the base in 2017 on a government aircraft.
