Migrants mostly form Central America wait in line to cross the border at the Gateway International Bridge into the US from Matamoros, Mexico to Brownsville, Texas, on March 15, 2021. – It’s the new normal for migrant families under President Joe Biden, after the harsh “zero tolerance” approach of Donald Trump dashed the dreams of hundreds of thousands hoping to escape endemic poverty and violence in Central America. Biden’s pledge of a more humane approach though has sparked a new rush to the border, threatening to become a huge political liability. Republicans are accusing him of opening the country’s doors to illegal border-crossers and sparking a “crisis” on the US-Mexico frontier, marked in Texas by the meandering Rio Grande river.
