Reporter: Donald Trump delivered the darkest inaugural address in history. This American carnage stops right here and stops right now. Reporter: The carnage would come. And it would be brought on in large measure by trump himself. You'll never take back our country with weakness. Reporter: Democracy assaulted and the capitol invaded by followers of a president who refused to admit he lost. Between his tumultuous first moments and his disastrous final days, Donald Trump treated the presidency like the world's greatest reality TV show and commanded the world's attention along the way.

There were bold moves as when he shocked the world by meeting one-on-one with dictator Kim Jong-un, even becoming the first president to step foot in north Korea. His white house was anything but stable. At home the man who promised to hire the best people churned through top advisers at a record rate.

They are dying. That's true and it is what it is. Reporter: With the virus raging, trump campaigned hard for re-election. That is a lot of people here today.
