Democratic front runner Joe Biden and close rivals Elizabeth Warren and Bernie Sanders have clashed over healthcare at the party’s third debate.
The debate in Houston, Texas was the first time the three presidential hopefuls faced off on stage.
Only the 10 highest-polling Democrats were eligible to take part.
Former Texas lawmaker Beto O’Rourke drew some of the biggest applause of the night with an impassioned plea for gun control.
Vice-president under Barack Obama, Mr Biden is leading current polls by a considerable margin.
