United States President Donald Trump has hinted that he may accept defeat by Joe Biden as media declared the Democrat the winner in Georgia while the counting was still going on, solidifying his lead in the electoral college.

Trump, who has so far refused to concede the election to Biden and has vowed to continue to challenge some of the results in courts, said on Friday while discussing the possibility of a coronavirus-induced lockdown, "Whatever happens in the future, who knows, which administration will be, I guess time will tell."
