Ten Democratic presidential hopefuls have clashed in a televised US debate that laid bare the party’s deep divisions over how best to win in 2020.
Elizabeth Warren and Bernie Sanders, the most liberal candidates in the crowded field, were under attack from their more moderate colleagues.
The three women and seven men on stage in Michigan debated healthcare, border policy and how to defeat Donald Trump.
Ten more Democrats, including Joe Biden and Kamala Harris, will spar on Wednesday.
The winner of the Democratic presidential nomination will be crowned next July at the party convention. The presidential election will take place months later, in November.
Several candidates began the debate in Detroit by criticising the policies of Ms Warren and Mr Sanders as unrealistic and not the best way for the party to defeat President Trump.
Who was on stage?
The line-up was chosen at random by CNN:
Massachusetts Senator Elizabeth Warren
Vermont Senator Bernie Sanders
South Bend, Indiana, Mayor Pete Buttigieg
Former Texas Congressman Beto O’Rourke
Minnesota Senator Amy Klobuchar
Ohio Congressman Tim Ryan
Former Maryland Congressman John Delaney
Montana Governor Steve Bullock
Former Colorado Governor John Hickenlooper
Author Marianne Williamson
What was the key flashpoint?
Healthcare, which has been an important issue for Democrats and was a focus during last year’s mid-term elections, was a point of contention on Tuesday night.
The first question posed to the candidates was whether Mr Sanders’ plan for a single-payer health system, Medicare for All, would be “political suicide”, but healthcare was a recurring topic throughout the debate.
The candidates sparred over enacting Medicare for All versus expanding on President Barack Obama’s signature policy, the Affordable Care Act, which extended health insurance coverage in 2010.
Mr Ryan and Mr Delaney, who has worked in the healthcare industry, were among those who attacked Mr Sanders’ plan, saying it would negatively impact on working-class Americans by taking away their employer-sponsored health benefits.
Mr Sanders focused on how millions of Americans remain underinsured or uninsured while the health industry makes billions in profits.
Ms Warren sought to refocus the matter slightly, saying that no Democrat is “trying to take away healthcare from anyone”, and that Democrats “should stop using Republican talking points” to discuss with each other.
What were the other clashes?
The 10 candidates on stage also differed on how to handle the crisis at the US-Mexico border.
Mr Buttigieg and Mr O’Rourke – who is from the Texas border region – offered policies to change the existing systems, but said crossings would remain illegal.
But the more liberal lawmakers, Ms Warren and Mr Sanders, both emphasised that families arriving at the border should not be criminalised.
“I’ve seen the mothers, I’ve seen the cages of babies,” Ms Warren said. “We must be a country that every day lives our values and that means we cannot make it a crime when someone comes in.”
Mr Ryan contended that such proposals would only incentivise people to enter the country illegally.
The candidates also tackled issues of race, with Mr O’Rourke and Ms Williamson calling for reparations – a repayment to black citizens for slavery.
Others, like Ms Klobuchar, proposed policies that would benefit all Americans, like better education and wages for teachers.
The 10 hopefuls largely agreed when it came to gun violence, dark money in politics and the need to address climate change.
