Democratic debate: Protesters interrupt Joe Biden during his closing segment

The protesters who interrupted Joe Biden earlier were reportedly shouting: "We are DACA recipients. Our lives are at risk!"

And that brings the third Democratic debate to an end - stay tuned for analysis on who the big winners, and the big losers, were on the night.

It was the first time the 10 main contenders had faced off on stage together, meaning we were almost certainly seeing the eventual Democrat challenger to Donald Trump - and it was often an intense and bad-tempered affair. But who came out best? Clark Mindock gives the contenders the once-over:

One issue grabbing attention had only a tangential link to the debate itself - an attack ad running in the commercial slots targeting Alexandria Ocasio-Cortez. While she's used to being a target of conservative attacks, the latest one is particularly shocking.

The advert - apparently released by a group called New Faces GOP - shows a picture of AOC on fire against footage of blindfolded skulls. The implication is that the Democratic congresswoman's avowed socialism and policies like the Green New Deal and universal healthcare will lead inevitably to scenes akin to the killing fields created by the Khmer Rouge in Cambodia in the 1970s.

Clark Mindock has the story:

AOC had her own take on the disturbing ad:

Joe Biden was at the centre of the most intense clashes tonight, but he probably did enough to keep his frontrunner status, says Andrew Buncombe, who was inside Texas Southern University to watch events unfold.

While the Democrats slugged it out in Texas, Donald Trump was giving a speech to a dinner of Republican supporters in Baltimore, a city he recently described as a "disgusting, rat and rodent infested mess" where "no human being would want to live" - not a slogan the city's tourist board is likely to adopt any time soon.

In a rambling 68-minute speech, he boasted about slashing regulations - including the Waters of the United States legislation that protected America's waterways from pollution - said his tax cuts had saved the average family $3,000 a year, and once again tried to take credit for Barack Obama's Veterans Care Act, one of the few of his predecessor's policies he seems to approve of.

He also managed to mispronounce his vice-president's name:

President Trump's vermin-evoking assessment of Baltimore was not lost on protesters awaiting his arrival:

In one of the more bizarre moments of the night, Joe Biden suggested parents should play records for their children to help them at school school.

The former vice president said: "Play the radio, make sure the television - excuse me, make sure you have the record player on at night, the phone - make sure that kids hear words, a kid coming from a very poor school, a very poor background will hear 4 million words fewer spoken by the time they get there."
