evidence: Analysis: Biden claimed, without apparent evidence, that children "starved to death" in Mexico under Trump’s 2019 policy allowing border officers to return non-Mexican asylum seekers to locations in Mexico as their claims are adjudicated in immigration courts. Asked for evidence of such deaths, a White House official referred to reports of "widely reported treacherous conditions at camps along the border on the Mexican side that formed as a result of the Trump administration’s use of the Migrant Protection Protocol, more commonly known as ‘Remain in Mexico.’" A nurse, for instance, told Reuters that in the camps, "she saw breastfeeding mothers so dehydrated that they could not nurse their babies and parents chewing up donated pizza into mush to feed their infants. Some children were showing early signs of malnutrition." One woman in the camp told the Guardian: "We've gone hungry. We've been cold. We've had to bathe in the river. This is a desperate place." The American Immigration Council also reported on the case of a woman who feared her daughter would die of starvation. These reports are certainly compelling, but none documented the deaths of children by starvation.
