Dramatic moment Trump fan collapses at Wisconsin rally as crowd prays

Donald Trump interrupted a campaign speech in Wisconsin to call for help on Saturday as some of his supporters began collapsing in the tightly-packed audience.

More than 7,000 people had arrived to see the former president give his fourth election rally of the campaign in the hotly contested state at the airport in Mosinee.

Many were warmly-dressed on a chilly day in Wisconsin but the sun beat down on the airport asphalt as the GOP candidate spoke for more than 90 minutes.

Some raised their hands in prayer as EMTs tried to insert an I/V line into one struggling woman who had fallen to the ground.

'Make some room for them so they can get out and hopefully come back before we've finished,' Trump told them. 'Because we can stay here all day as far as I'm concerned.'

The ex-president was promising to abolish the Department of Education when he heard someone scream 'Medic, Medic!' from the crowd.

'Medic please,' Trump said from the podium. 'Doctor?' Thank you very much. Take your time. Thank you doctor.

'We've got the greatest service here,' he added to applause as EMTs fought their way through the crowd.

'It's just amazing the way they are right on it. And some people are out here for three days so it's really incredible that things like this don't happen more often.

But they always turn out to be good, they're excited by what we're doing because we're taking our country back from these lunatics. Take your time doctor. Thank you very much.'

Other casualties were escorted to the sidelines and checked over by health professionals at the event which opened with a performance by country singer Gretchen Wilson.

'Doctors thank you very much we appreciate it,' Trump told them from the stage. 'If anything happens let us know.'

The ex-president apologized for speaking from behind a plexiglass screen following the attempt on his life at a July 13 rally in Butler, Pennsylvania.

'It's a little tough life. It's not the easiest,' he told his audience. 'You get shot at, other things happen, other routine events happen. But we're going to do it for one reason.

'Just a little while ago, a reporter said, 'Sir If you had to do it again, would you do it again?' I said, 'Absolutely, because we're going to make America great again. And that's better than my life'.'

The crowd trouble at Mosinee came just two weeks after the ex-president stepped out from behind his bulletproof screen to help an elderly woman who had collapsed at his rally in Asheboro, North Carolina.

Trump spotted her faint as he spoke in hot sunshine at Asheboro Regional Airport in his first outdoor rally since the attempt on his life.

'Hi darling, are you okay? Drink plenty of water,' he told the 78-year-old.

She appeared stunned that she came face-to-face with the speaker, telling him: 'Oh my gosh, I'm fine.

'I'm just an old woman and I had to come see you,' she added.

Trump had been speaking about how he sponsored athletes during his business days, but stopped as people in the crowd could be heard shouting 'medic!'

'A doctor, please...' Trump called from the podium before heading into the crowd.

The former president speculated that high temperatures were the cause, as he said before wading into the crowd that 'it is very hot here, I notice.'

He praised his fans for camping out for a long time to catch a glimpse of him at his events, telling them:

'You know, they come two, three days early and it's a lot of stress, we lose them.

'The only ones we don't lose are the front row Joes, I don't know what they have going, they have something going here.'
