Pro-Trump protesters chased Elizabeth Warren through Reno airport on Wednesday shouting 'stop the impeachment' as she arrived in Nevada for a rally.

Activists wearing MAGA hats and waving Trump-Pence banners also yelled 'Pocahontas go home' at Warren, in reference to a label the President gave her mocking her claims to Native American heritage.

Warren - who recent polls show has leapfrogged Joe Biden to become frontrunner for the Democrat nomination - smiled, waved and told the demonstrators it was 'nice to see you' before getting into a waiting car.

Biden's ratings have been damaged by the Trump impeachment scandal and his dealings with Ukraine during his time as Vice President.

Elizabeth Warren arrived at Reno airport Wednesday where she was confronted by around a dozen pro-Trump protesters who heckled her as she walked through

Footage of the incident was shared on Twitter by the Nevada GOP.

Alongside was a message that said: 'Nevadans greeted Elizabeth Warren in Reno and let them know exactly how they feel about the Democrats’ despicable attempt to impeach Donald Trump and undo the 2016 election.'

Nevada Republican Party state chairman Michael J. McDonald also tweeted the video, writing: 'Welcome to Reno Elizabeth Warren. This is team Trump country!'

Reno airport has since issued an apology to Warren, saying the protesters did not follow the permit process to rally inside the building.

'Airport Police weren't given prior notice of the arrival... and the airport's attorney will be investigating the incident,' a spokesman wrote.

In the footage, Warren and three staffers can be seen walking into the arrivals lounge of Reno airport before a group of around a dozen pro-Trump supporters begins shouting at her.

Waving Trump-Pence banners, the demonstrators yelled out 'stop impeachment' and 'go home Pocahontas' in reference to the mocking label Trump uses to refer to her. It's worth noting Senator Warren is actually powerless when it comes to deciding whether the President is impeached. Under the framework of the Constitution, the House, not the Senate votes to impeach a president for 'high crimes and misdemeanors'

Warren climbed into her car outside the airport and was driven away before security arrived to break up the demonstrators

As she pulls her travel case past the airport slot machines the group follows her, shouting about the impeachment inquiry and hurling insults.

At one point she waves and can be heard saying: 'Nice to see you.'

She then walks outside and climbs into a red minivan before being driven to a rally in Carson City, around half an hour away.

While there, she was confronted by yet more protesters, including several who made it inside the hall where she was speaking.

Waving a banner reading 'Keep America Great', one man shouted profanity and swore at Warren as she spoke before being taken out by security.

The Nevada GOP tweeted out the video, which was also shared by Nevada Republican Party state chairman Michael J. McDonald

Reno airport said the activists did not apply for a permit to protest inside the terminal, apologised to Warren and said an investigation has been launched

'I understand Donald Trump and his supporters are getting really nervous,' she joked with the crowd afterwards.

During the rally she spoke to 1,500 supporters about her plan to break up big banks and corporations in order to boost America's 'forgotten' middle classes.

She briefly touched on the question of impeachment, saying she hopes 'no one takes it lightly.'

House Democrats are currently leading an impeachment inquiry into Trump, which could form the basis of articles of impeachment - the first step in ousting him.

It's worth noting Senator Warren is actually powerless when it comes to deciding whether the President is impeached. Under the framework of the Constitution, the House, not the Senate votes to impeach a president for 'high crimes and misdemeanors.' It’s up to the House to decide what that means.

Trump has described the inquiry as 'treason' and a 'coup' while insisting that he has done nothing wrong.

The inquiry relates to a call he had with Ukraine's new leader in which he asked for a 'favour' in digging up dirt on potential rival Joe Biden.

At the same time the US was holding back aid payments to Ukraine, leading to accusations of a 'Mafia-style' shakedown.
