Watch | Sainthood for Mother Teresa to be approved on Tuesday

Mother Teresa, the nun who cared for the poorest of the poor across India, will be given official approval to be declared a saint on Tuesday. Pope Francis had signed off on the miracle needed for sainthood last December. Though Mother Teresa's canonization was long expected, the timing has been unclear. The date and venue for the canonization ceremony will be announced at the Tuesday consistory in the Vatican, presided over by Francis.
