WASHINGTON (AP) — Bernie Sanders is calling for decriminalizing illegal border crossings, backing an idea that exposes the Democratic presidential primary’s ideological divides. Sanders said Thursday: “Unauthorized presence in the United States is a civil, not a criminal, offense.” Elizabeth Warren also has called for repealing the criminal prohibition against crossing the border illegally. Pete Buttigieg wouldn’t do so in cases involving “fraud,” and Joe Biden hasn’t fully backed decriminalization.
