The two Guatemalan children died after crossing the border while they were under United States custody.
Catarina Alonzo, mother of eight-year-old Felipe Gomez Alonzo, one of two children, said that her son was in good health when he left Guatemala with his father on their journey hoping to migrate in the USA.
She said that her son was doing well every time he and his father called home during their journey. She said that the last time she spoke to Felipe, he was in Mexico City on the US border and was eating chicken.
US authorities said the boy was suffering from the flu when he died last Monday in Alamogordo, New Mexico.
President Trump seeks to dismiss the responsibility for the deaths of two children in the United States by saying they were "very sick" upon arrival, even though immigration officials said the two children were successful. according to the first health examinations.
