The Biden Administration again criticized the Nicaraguan government on Tuesday for “unjustly” incarcerating Roman Catholic bishop Rolando Álvarez to decades in prison for alleged treason, demanding the current regime free the religious leader immediately and without conditions.

State Department spokesman Matthew Miller called on Nicaragua’s President Daniel Ortega and Vice President Rosario Murillo to release Álvarez of the Catholic Diocese of Matagalpa, who has spent more than 500 days in La Modelo Tipitapa — one of Latin America’s most notorious prisons.

“During that time, Nicaraguan authorities have kept Bishop Álvarez in isolation, blocked independent evaluation of the conditions of his imprisonment, and released staged videos and photographs that only increase concerns about his well-being,” Miller said.
