The Biden administration has announced that it will continue building sections of the border wall in order to address the surge in migrant crossings from Mexico. This decision aligns with former President Trump's policy of building border barriers, despite Biden's earlier proclamation against using taxpayer dollars for the wall. Immigration is expected to be a prominent issue in the U.S. presidential race, and the decision may face criticism from left-leaning supporters. The Biden administration has also maintained a public health order allowing the expulsion of migrants and implemented new rules for asylum seekers. Migrant numbers have recently been rising, and there is a backlog of immigration cases.
