A highly placed Vatican source told LifeSiteNews that Cardinal Gerhard Müller, together with his much-experienced three CDF priests, were dismissed by Pope Francis because they all had tried to follow loyally the Church's standing rules concerning abusive clergymen. In one specific case, Müller opposed the Pope's wanting to re-instate Don Mauro Inzoli, an unmistakably cruel abuser of many boys; but the Pope would not listen to Müller. In another case, the Pope decided not to give a Vatican apartment to one of Müller's own secretaries, but to the now-infamous Monsignor Luigi Capozzi, in spite of the fact that someone had warned the Pope about Capozzi's grave problems. The Vatican source also said that it was known to several people in the Vatican that some restrictions were put on Cardinal McCarrick by Pope Benedict XVI, and he thereby confirms Viganò's own claim.
