Williamson is told to stop talking about politics and history. A communique from Bishop Fellay:

It has come to our attention that Bishop Richard Williamson, a member of our Society, granted an interview to a Swedish network. In this interview, he also commented on historical issues, especially on the genocide of Jews by the National-Socialist regime. It is obvious that a bishop speaks with religious authority solely on matters of faith and morals. Our Society claims no authority over historical or other secular matters.

The mission of the Society is the offering and restoration of authentic Catholic teaching, as reflected in the traditional dogmas. We are known, accepted and appreciated worldwide for this.
We view this matter with great concern, as this exorbitance has caused severe damage to our religious mission. We apologize to the Holy Father and to all people of good will for the trouble it has caused.
It must remain clear that those comments do not reflect in any way the attitude of our community. That is why I have forbidden Bishop Williamson to issue any public opinion on any political or historical matter until further notice.
