America's oldest Traditional Catholic newspaper, The Remnant, has penned an open letter asking the Trump Administration to investigate the Vatican's alliance with the Democratic Party et. al. The letter, which will appear in the next print edition, can be viewed online here.
I do support such an investigation by the U.S. Government at this time, especially when the abdication of Benedict XVI was fishy, and a priest in Colombia was suspended by his bishop recently for preaching the truth on Catholic Holy Matrimony.
If a criminal investigation confirms that Jorge Bergoglio is not the legitimate Successor of Peter (a.k.a. an antipope), he should be captured by the Special Forces and brought to justice just like Bin Laden. I am pretty sure a Traditional Catholic President would do so without hesitation.
