A Mexican-American woman and fervent Trump supporter was caught on camera chasing down undocumented migrants to try and stop them crossing the border into the US.

Paloma Zúñiga was even seen shoving a child as she tried to stop the group of four Mexicans, who had just crossed the Colorado River before touching ground along the dirt border terrain in Yuma, Arizona.

But Zúñiga, who was born in Mexico City and became a naturalized US citizen, says she did so do because they were breaking the law and risking the lives of young children.

'Go back! Go back! This is not your country,' the self-styled AZ Patriot can be heard shouting in footage obtained by USA Today.

Paloma Zúñiga, who was born in Mexico and later became a naturalized United States citizen, was filmed attempting to stop undocumented migrants after they crossed the Colorado River and stepped foot in Yuma, Arizona

Zúñiga told Telemundo that she opposed migrants crossing illegally into the United States 'because they are exposing children'

'Where [are you going]? Where [are you going]? You go back or we will all grab you,' Zúñiga said as she sidestepped in front of the migrants.

'Go back! You cannot enter here, you country is not here. You have to enter with papers,' she then added before she pushed one of the children.

Zúñiga, who bills herself as a political activist, told Telemundo on Monday she was on site as a guest the AZ Patriots, an anti-immigration group that was filming a documentary in June when she came across the migrants.

'The message that I wanted to send is that it is wrong that they are crossing the border that way because they are violating the laws of the country,' she said.

'They are also exposing themselves and because they are exposing children.'

Pro-Trump Zúñiga moved from Mexico to the United States and later became US citizen

Zúñiga said she might have been wrong for the aggressive way in which she confronted a migrant child who she pushed after he and several other undocumented immigrants cross the Mexico-United States border

According to her web page, palomafortrump.com, Zúñiga moved to the United States legally at the age of 10 with her mother after he father passed away.

Her mother then married an American man, who Zúñiga says 'gave me the blessing of becoming a U.S. Citizen'.

'We waited for almost 10 years to finalize our citizenship, we paid our dues, we waited in line,' she wrote.

'And I feel every person who comes to America should not only do the same, but also learn the language, assimilate the culture, respect and love America like I do.'

Zúñiga, who says in the past she has spent time along the Mexico-United States border in Tijuana providing assistance to migrants, admitted that perhaps she was not right in the aggressive manner in which she approached the child.

'I would like to tell him that in no way was it my intention to scare you or hurt you.'
