Pope Francis has appointed Filipino priest Romeo Convocar as apostolic administrator of the Archdiocese of Agaña in Guam.   Convocar’s appointment came after the resignation of American Archbishop Michael Jude Byrnes due to medical reasons, according to the Catholic Bishops' Conference of the Philippines (CBCP).   Prior to his appointment, the Filipino priest had been serving as the vicar general of the archdiocese in U.S. territory.   Convocar will oversee the ecclesiastical territory until the nomination of a new archbishop, the CBCP said.
