A student protester has been dragged off stage after criticizing Hillary Clinton at a campaign event in Iowa.

Kaleb Vanfosson, the president of the Young Democratic Socialists group at Iowa State University, spoke on stage prior to a Bernie Sanders address at the Iowa State Center in Ames on Saturday night.

Footage of the incident shows Vanfosson, who was scheduled to talk about how Sanders and Clinton were uniting voters, went off-script and ranted about Hillary's flaws.

However, shortly into the speech he began criticizing Hillary, which led to a staffer member rushing out (left) to escort him off stage (right)

'There are a lot of important issues being talked about this election cycle, and one of the biggest ones is student debt,' Vanfosson said.

'In 2012, 71 percent of college students in America graduated with student loan debt, and the average amount of that debt was $26,000 per student.

'While the part-time reality TV show star and full-time bigot Donald Trump thinks brave, hard-working immigrants are what’s wrong with our country, he is failing to even talk about this issue.

'But unfortunately Hillary doesn’t really care about this issue either. The only thing she cares about is pleasing her delegates – the billionaires who fund her.'

He then went on to claim the only people who can 'trust Hillary' are: 'Goldman Sachs... Citigroup... the military industrial complex... and her good friend, Henry Kissinger.'

'She is so trapped in the world of the elite that she has completely lost grip of what it is like to be an average person,' the student politician said, before he was hustled off stage.

Clinton was not present at the event but Sanders took to the stage after the incident.

Sanders, who was beaten by Clinton to be the Democratic nominee, urged voters to get beyond 'liking' Hillary and to instead vote based on issues.

'Get beyond personality; that means taking a hard look at what the candidates stand for,' he said, according to the Iowa State Daily.

'We're not running here for class president of the local high school.

'This is not a popularity contest. Our job right now in these very difficult times is to bring people together.'
