RIYADH, Nov. 22 (Reuters) - US President Donald Trump went golfing after making a brief online appearance at the G20 summit on Saturday (Nov 21), an event hosted by Saudi Arabia but staged virtually because of COVID-19.

Trump, who has still not accepted defeat following Joe Biden's victory in the Nov 3 presidential polls, spoke following the opening of the two-day virtual summit.

A source with access to the online sessions, which were closed to the media, reported that Trump "said that he had done an absolutely incredible job during his term, economically and with the pandemic".

"It's been an honour working with you and I look forward to working with you in the future and for a long time," he said according to a second participant.

In a summary released late on Saturday, White House Press Secretary Kayleigh McEnany said the president discussed the need to work together to restore economic growth.

After speaking, Trump was substituted by Treasury Secretary Steven Mnuchin as the other world leaders had their say.

Later, he left the White House and headed to his golf course in Virginia, not far from Washington.

He was met by a handful of supporters with Trump flags, one carrying an effigy of the 45th US president and a "Four More Years" banner.

Another sign, however, showed a slice of bread marked with the words: "Face it. You're Toast."
