NEW YORK (AP) — On a recent afternoon, Mahmoud Khalil sat in his Manhattan apartment, cradling his 10-week-old son as he thought back to the pre-dawn hours spent pacing a frigid immigration jail in Louisiana, awaiting news of the child’s birth in New York. For a moment, the outspoken Palestinian activist found himself uncharacteristically speechless. “I cannot describe the pain of that night,” Khalil said finally, gazing down as the baby, Deen, cooed in his arms.
