Honest questions, nothing is more dangerous to them.

On August 25, 2018, Viganò published an 11-page letter accusing Pope Francis and numerous other senior Church leaders of concealing allegations of sexual misconduct against then-cardinal Theodore McCarrick. Viganò stated that Pope Benedict XVI imposed sanctions on McCarrick in response to accusations that were made against him, but that Pope Francis refused to enforce them and that he made McCarrick an important advisor. Viganò called on Francis to resign. The letter provoked diverse reactions within the Church, with some expressing support for the allegations and calling for further investigation and others defending Francis, questioning the claims made in the letter, and attacking Viganò's credibility. After the publication of the letter, Viganò continued to issue public statements.
