Republican presidential hopeful Jeb Bush has been forced to abandon a rally early because of a protest from Black Lives Matter.

The former governor of Florida was in Las Vegas for a town hall meeting on Wednesday when he answered a question on racial inequality.

An advocate in the crowd of around 150 then started to chant their slogan, so he quickly ended his speech and left the venue without making a final statement or shaking hands with members of the audience.

The music he plays when he walks off stage is heard in the background of a video as the civil rights group keep shouting the mantra.

It comes just four days after Democratic candidate Bernie Sanders suffered the same fate because of the group's actions during an appearance in Seattle.

In the past week members have also turned up to one of Hillary Clinton's events.

Bush was asked about the racial disparities in the criminal justice system that have been exaggerated by black men being killed by white police officers.

He said that 'these problems have gotten worse in the last few years' and that communities 'no longer trust the basic institutions in our society that they need to trust,' according to CNN.

The GOP prospect then said 'perception becomes reality, and there really is racism in America'.

Bush has received criticism from the Black Lives Matter movement.

He backed Democratic presidential candidate Martin O'Malley for telling protesters that 'all lives matter.'

In a statement, his campaign team said they had spoken to members of the group before the rally.

On Tuesday he attacked Democrat Hillary Clinton for her handling of Iraq as secretary of state, saying she must share the blame for the rise of Islamic State militants, in a prelude to a potential general election matchup in 2016.

Black Live Matter's latest move against a candidate came as protesters staged their fifth night of demonstrations in Ferguson to mark the one-year anniversary of Michael Brown's death.

Around 100 protesters gathered along West Florissant Avenue in Ferguson late Tuesday in a demonstration that was decidedly smaller and calmer than others on recent nights.

Attendees mostly mingled quietly along the side of the road. Some chanted, and a few held signs.

Police officers, most wearing riot gear, appeared to outnumber protesters.

Donald Trump picked a fight with the Black Lives Matter racial-justice movement on Tuesday - telling reporters that Sanders was 'weak' for allowing activists from the group to hijack an event on Saturday.

The protesters stormed a Seattle stage and took Sanders' microphone, ending the event before it had started.

Trump suggested that he would welcome a physical confrontation with the social justice warriors if he were put in the same position.

'I don’t know if I'll do the fighting myself, or if other people will, but that was a disgrace,' Trump told reporters during a press conference before a Michigan campaign speech.
