The State Department will allow President Raúl Castro’s daughter to travel to Philadelphia to receive a gay civil rights award. Mariela Castro, director of Cuba’s National Center for Sex Education, was granted a diplomatic visa to attend United Nations meetings in April, but the State Department did not issue a second visa she requested to attend the Equality Forum 2013 Summit this weekend. Cuban diplomats cannot travel more than 25 miles without prior authorization. Ms. Castro is considered an international leader in the issue of rights for gay and transgender people. The Equality Forum received word on Monday that the State Department decided to lift the 25-mile restriction. “Better judgment prevailed,” said the group’s director, Malcolm Lazin. The State Department did not explain the reversal.
