ROME — Pope Francis will elevate Archbishop Wilton Gregory of Washington to cardinal next month, making him the first African American to hold the title.

Gregory is one of 13 cardinals in the new class Francis announced Sunday, a promotion that comes as he is trying to rebuild trust in an archdiocese rocked by sexual abuse cases.
