DAHLONEGA — The flow of ideas spun in different directions on a dicey topic at the University of North Georgia on Wednesday. Students used their noon lunch hour at the Dahlonega campus to grapple with the dilemma facing the nation after the administration of President Donald Trump rescinded the Deferred Action for Childhood Arrivals program two weeks ago. The action means that some 800,000 illegal immigrants brought into the country as minors could be rounded up and deported unless Congress addresses the issue within the next six months. A few dozen students gathered at Young Hall to take part in the debate on DACA. The program is part of weekly “Crossfire” discussions presented by the UNG Political Science Student Association.
