Alexandria Ocasio-Cortez was seen wiping tears from her face after using the death of a seven-year-old migrant child to demand an end to funding for the nation’s border agency.

At the event on Capitol Hill in Washington DC, the New York congresswoman said US Immigration and Customs Enforcement (ICE) did “not deserve a dime”, until it showed it cared about human rights.

“Not only will we not agree to fund [ICE], but we are here to say that an agency like ICE, which repeatedly and systematically violates human rights, does not deserve a dime,” she said.

According to Mediabite, she added: “Until they can prove that they are honouring human rights, until they can make a good-faith effort to expand and embrace immigrants, the immigrants in this nation that have always been a part, and have always been a core element of American democracy, until they can prove good faith to an American ideal they do not deserve any resources for their radical agenda.”

At the event, organised by progressive group MoveOn and which was also attended by fellow new Democratic congresswomen Ayanna Pressley, Rashida Tlaib and Ilhan Omar, Ms Ocasio-Cortez referred to the death of Guatamalan youngster Jakelin Caal Maquin, who died in December after she and her father were picked up as part of a group of 163 undocumented migrants in a stretch of the New Mexico desert.
