she is a white nationalist

Conrad Black, the convicted US criminal
He's been pardoned.
and who denounced Canadian citizenship
For the record, Black renounced his Canadian citizenship because Jean Chretien was preventing him from accepting a Lordship from the Queen based on an old law from the 1800s.
