Joe Biden faces attack in Democratic TV debate

US former vice-president Joe Biden has come under attack from other democratic 2020 candidates in a televised debate.

The party’s aspirants shared a stage in Detroit with nine other presidential hopefuls and there were several sharp exchanges on healthcare and the border.

In an echo of the last debate in June, Senator Kamala Harris again launched an assault on Mr Biden’s record on race.

But she had to defend her actions against drug offenders when she was a prosecutor in California.

All eyes were on Mr Biden and Ms Harris when they took the stage.
