Vibeke Hein Baera told Norway's NRK news organization she received a number of death threats and learned there was a price on her head, through text messages, telephone calls and face-to-face conversations, but added most people understood even Breivik, who killed 77 people in July, deserved a fair trial.
"It created fear for my children and felt really horrible," she said.
Baera was advised by the police on safety measures to take, the Norwegian news agency NTB said Tuesday.
"This was taken very seriously by police, and I have felt secure all along in the way the police have handled our safety," she said.
