Looks like Vigano poked the bear one time too many. Cardinal Burke had better tread lightly:

Archbishop Carlo Maria Viganò on Thursday claimed that the Vatican’s Dicastery for the Doctrine of the Faith has initiated proceedings against him over the alleged crime of schism.
Citing a document he published on his website and posted onsocial media, the former papal nuncio to the United States wrote that he was summoned to Rome on June 20 to face an extrajudicial penal process for the charges.
“I have been summoned to the Palace of the Holy Office on June 20, in person or represented by a canon lawyer,” the prelate wrote on X. “I assume that the sentence has already been prepared, given that it is an extrajudicial process.”
The specific charges outlined against Archbishop Viganò involve making public statements that allegedly deny the fundamental elements necessary to maintain communion with the Catholic Church. This includes denying the legitimacy of Pope Francis as the rightful pontiff and outright rejection of the doctrines established during the Second Vatican Council.
