Democratic presidential candidates have given their reaction to a warning by former President Barack Obama against moving too far left in politics.
Mr Obama's rare intervention into the Democratic race was a talking point at campaign events on Saturday.
Some Democrats called for unity, while others defended their policy agenda.
Nearly 20 candidates remain in the running and there is much debate over the best approach to taking on President Trump next year.
Speaking at a fundraising forum in Washington, the former president - considered a moderate - cautioned candidates against pursuing polices that were not "rooted in reality".
Mr Obama, who was in office from 2009 to 2017, said "ordinary Americans" didn't want to "completely tear down the system".
