Writing in L’Osservatore Romano, Cardinal Roger Mahony, who served as archbishop of Los Angeles from 1985 to 2011, discussed the plight of “DREAMers”: persons who were brought illegally to the United States by their parents when they were children. “While President-elect Donald J. Trump has pledged to implement several severe immigration policies, including the deportation of 11 million undocumented immigrants and the construction of a wall on the Mexican border, the most pressing and imminent challenge his incoming administration presents on this critical issue is its promise to rescind the DACA program,” Cardinal Mahony wrote.
