US President Joe Biden endorsed Vice-President Kamala Harris as the presidential nominee of the Democratic Party after opting out of the race on Sunday, ending his re-election bid after a recent disastrous debate with Donald Trump that raised doubts about Biden's fitness for office.
The President called upon his party to unite behind Harris, while the Vice-President praised Biden’s “selfless and patriotic act” and said she intends to “earn and win” her party’s nomination.
