Watch Biden’s full speech at the Democratic National Convention

An emotional US President Joe Biden received a standing ovation as he gave his departure speech on the first day of the Democratic National Convention in Chicago on Monday, endorsing Vice President Kamala Harris, who later thanked him for being an "incredible" president. "I love you," a tearful 81-year-old US president told the crowd amid thunderous applause, less than a month after he withdrew from the race for president against Republican nominee Donald Trump.
