US President-elect Joe Biden says it's a "good thing" President Donald Trump won't attend his inauguration on 20 January.
Mr Trump has announced he will skip his successor's inauguration, becoming the first incumbent president since Andrew Johnson in 1869 - 152 years ago - to do so.
Like Mr Trump, Mr Johnson was also impeached.
In a Friday tweet, Mr Trump said: "To all of those who have asked, I will not be going to the Inauguration on January 20th".
Mr Biden welcomed the announcement a short time later.
"I was told on the way over here that he indicated he wasn't going to show up at the inauguration," he told reporters in Wilmington, Delaware.
"[It's] one of the few things he and I have ever agreed on. It's a good thing, him not showing up. He's been an embarrassment to the country."
"He exceeded even my worst notions about him," Mr Biden added. "He's one of the most incompetent presidents in the history of the United States of America."
The president-elect said Vice President Mike Pence would be "welcome" at his inauguration.
It came as US House Speaker Nancy Pelosi said she had spoken with the nation's top military leader about ensuring that an "unhinged" Mr Trump does not launch a nuclear attack in his final days in office.

The top Democrat in Congress said she talked with Joint Chiefs Chairman Mark Milley "to discuss available precautions for preventing an unstable president from initiating military hostilities or accessing the launch codes and ordering a nuclear strike."
On Thursday, Mr Trump came closer than ever to a formal concession that he lost the election, a day after he incited a mob that stormed the US Capitol as Congress certified Mr Biden’s win.
But while he says he is now focused on a “smooth, orderly and seamless” transition of power, much about the remaining two weeks of his presidency appears uncertain.
