Joe Biden managed to do in a single day what his 45 predecessors had not done in 232 years. On his first day in office, the new president split the Catholic hierarchy acutely, decisively, and publicly.
Keep in mind that Catholic bishops have a long history of neither "airing their dirty laundry" nor disclosing their differences. Unity and comity are valued highly. For example, no Catholic bishop publicly criticized Cardinal Theodore McCarrick until after his scandalous behavior became a matter of public record and salacious headlines.
