Kaci Hickox took her campaign against an Ebola quarantine out for a spin on Thursday.
The Maine nurse, openly defying an order to stay home after she treated patients in West Africa, sped off on a bike ride on a sunny morning with her boyfriend, Ted Wilbur.
Authorities in Maine are pursuing a court order to enforce the quarantine through Nov. 10. Hickox says she is completely healthy and free of symptoms, and that the quarantine is unnecessary and unconstitutional.
Hickox was kept in an isolation tent for three days after she returned to the United States last week. New Jersey Gov. Chris Christie let her go on Monday, and she was driven to Maine, which imposed its own quarantine.
Some states have gone further than federal health officials and ordered quarantines for health workers returning from Ebola-stricken countries in Africa, even when they show no symptoms and therefore would not be contagious anyway.
Late Wednesday night, with a state trooper looking on, Hickox stepped outside the house in Fort Kent where she has been holed up. She said: "I'm not willing to stand here and let my civil rights be violated when it's not science-based."
