Democratic presidential candidate Cory Booker was cut off mid-speech when a van crashed into the side of the Florida strip mall where he was holding a campaign event on Sunday.

Witnesses reported hearing screeching tires and seeing the silver Ford Windstar come 'flying' across the parking lot, before it collided with a structural beam right outside the building in Miami Gardens.

A video taking inside the event shows the moment Booker's speech was interrupted by the crash, with spectators jumping to their feet in panic.

New Jersey Senator and 2020 presidential candidate Cory Booker was giving a talk in Miami Gardens on Sunday about voter rights when the event was interrupted by a van crashing into the building

Photographs and video from local news site Local10 show the extent of the damage caused by the van as it slammed into the pole - sending bricks and debris flying.

The female driver of the vehicle was taken into custody for issues relating to traffic infractions, with police later confirming that the crash was an accident.

New Jersey Senator and 2020 hopeful Booker was in Miami to advocate for a recent constitutional amendment passed by Florida voters that restores voting rights to former felons.

After the crash shook the walls, organizers urged spectators to leave the Mo Space by Miami Soul Cafe where Booker had been speaking in case the building was unsafe.

Onlookers dialed 911 as the driver called for help from inside the van. The passenger was hospitalized for minor injuries.

It was soon confirmed that the crash was unrelated to Booker's event, and although no attendees were injured many were left shaken as Booker has received death threats from at least two South Florida men in the last six months.

However the Senator, who turned 50 on Saturday, remained calm and collected.

'I'm glad the people involved are safe and it's an unfortunate accident that happened,' he said.

'I have been a former mayor. We have dealt with a lot crises. The key is to remain calm and see what you can do to help other people,' Booker told Local 10's Liane Morejon.

Footage taken inside the event shows the moment the talk was interrupted by the crash. Spectators were evacuated as a safety precaution but the talk resumed a short while later

Booker is a self-proclaimed liberal who endorses abortion rights, affirmative action, criminal justice reform, path to citizenship for 'dreamers and federal marijuana decriminalization. If elected next year he would make history as the first unmarried president since Grover Cleveland in 1886

After a short delay he continued his speech and hung around afterwards to take photographs and answer questions from the some 30 voters who turned out to see him.

The Miami Gardens event formed part of Booker's Justice for All tour, which has taken him through key primary states including his home state of New Jersey, as well as Iowa, Georgia and Nevada over the past two weeks.

The event was billed specifically as a discussion of voting rights.

'I was so inspired by the leaders here in Florida who changed something that was put into place as a means of suppressing African Americans, specifically,' he said, referencing the amendment that passed in November.

'A century later, what was going on in Florida before you all did this incredible... statewide referendum, you literally had counties in this state where one out of every three African Americans could not vote because criminal justice wasn't equal.'

But he added that he believes the Republican-led Florida legislature is trying to undermine the measure.

'Democrats and Republicans came together to end the absurdity of having someone with a nonviolent drug conviction losing their voting rights for the rest of their life,' Booker said.

'So this most recent action by the House to try to put up financial barriers to those people who just had their rights restored is outrageous and unacceptable.'
