George Bush steps into US migration debate World April 18, 2021 WASHINGTON: Former president George W Bush has stepped into the US debate on immigration, saying migrants are "a force for good" and arguing for a gradual process to allow undocumented immigrants to earn legal status. Bush, a past governor of Texas -- a border state heavily impacted by migration -- made his points in an op-ed article in the Washington Post previewing his new book "Out of Many, One: Portraits of America’s Immigrants." The book, whose name comes from the nation’s Latin motto "E Pluribus unum," features portraits of immigrants done by Bush himself, who self-deprecatingly says he knows his paintings "may not set the art world stirring."
