Pope in hospital for 'scheduled tests'

(ANSA) - ROME, MAR 29 - Pope Francis went to Rome's Gemelli Hospital Wednesday afternoon for "some tests which had been scheduled previously", Vatican spokesman Matteo Bruni said.
    The pope, 86, has knee problems which have forced him to often use a wheelchair.
    He has said he might resign like his predecessor Benedict XVI if bad health makes it impossible for him to continue doing his job.
    Francis in December revealed that he has signed a letter of resignation to be used if he is unable to perform his duties for health reasons. (ANSA).
