Former US President Barack Obama and Michelle Obama have given impassioned endorsements of Kamala Harris on the second night of the Democratic National Convention.

They urged voters to back a “new chapter’ with her in back-to-back speeches that electrified the audience in a packed arena in Chicago.
In her speech Michelle Obama mocked Donald Trump directly, asking if he knew he was running for a “black job”, referring to being president.
The Republican candidate has come under fire for saying migrants are taking “black jobs” in the US.
The four-day convention formally anoints Harris as the Democratic presidential contender; Donald Trump had his convention last month after surviving an assassination attempt
