George Ganswein?? That is the guy became famous because he was then-Cardinal Ratzinger’s right hand man, and was said to be so handsome. The Vatican has never confirmed that he was in the SSPX seminary, so where does this statement, presented as a fact, come from? He’s a part of the Italian fashion industry. He’s been on the cover of Italian fashion magazines and the inspiration for fashion lines.
Hasn't denied it either.
Gänswein initially began his seminary training at the International Seminary of Saint Pius X in Switzerland. This was finally reported in 2009 by French magazine L'Express. No one at the Vatican has ever officially denied it. A two-year gap in the biography of Gänswein suggests this earlier seminary training was certainly a possibility. -Wiki
