Republican presidential hopeful Donald Trump's "cynicism is unbounded", US Vice-President Joe Biden has said.
Speaking at the Democratic National Convention, Mr Biden launched a scathing attack on the billionaire tycoon, accusing of him of being inconsiderate and out of touch with ordinary Americans.
"His lack of empathy and compassion can be summed up in a phrase I suspect he's most proud of having made famous: "You're fired."
"How can there be pleasure in saying you're fired? He's trying to tell us he cares about the middle class - give me a break.
"That's a bunch of malarkey. He has no clue about what makes America great. Actually he has no clue period."
In contrast, the vice-president sought to recast the image of Mrs Clinton as a remote establishment figure by maintaining that she could relate to the problems of ordinary citizens.
