YUMA, Ariz. – A major border city is on the brink of collapse as the migrant surge under President Biden's leadership overloads food banks and hospitals and threatens food security, a Yuma official told Fox News."Policies need to be changed when you see an unprecedented amount of people coming across the border that even supersedes what we saw under any of the other presidents for the past 30 years," Yuma County Supervisor Jonathan Lines told Fox News. "And they're coming because they said that Biden told them to come, that we have an open border."
