She told in a statement to DN that:
“I never would have associated with Mr. Epstein if I had been aware of the seriousness of the crimes he committed. I should have investigated his past more thoroughly, and I am sorry that I didn't” [...]
“Through years of work with questions regarding international health issues, I have witnessed first hand the kind of damage sexual assault does to women and children. We all have a responsibility to fight sexual assault, and to support the victims. I wish to express my deepest sympathy and solidarity to the victims of Jeffrey Epstein”
Crown Princess Mette-Marit of Norway met sex offender Jeffrey Epstein several times, both in the US and in Oslo, Norway, even after he admitted to sex crimes. She apologizes for not investigating his past.
