Earlier today, nurse Kaci Hickox went out for a bike ride in Maine, openly defying an Ebola quarantine by state officials.

She had been ordered her to stay in her home, with officials vowing to go to court to force her to stay there.

Now, Gov. Paul LePage says that "extensive negotiations" between the Health Department and Hickox have failed and that the state will exercise the full extent of its authority to address the threat to public safety.

Hickox has vowed to fight the quarantine, saying she has no Ebola symptoms and there is no scientific evidence that says she is a danger to the public.

Hickox spoke out last weekend against New Jersey Gov. Chris Christie (R) after the state placed her in a quarantine when she returned from treating Ebola patients in West Africa.

Hickox and her boyfriend rode their bikes in Fort Kent this morning, with police cruisers trailing them.

Shannon Bream sat down with Judge Andrew Napolitano today to get his take on the legality of the quarantine as Maine seeks a court order to keep Hickox in her home.

The judge said licensing authorities could go after her nursing license if Hickox agreed previously to abide by such a quarantine.

Napolitano said if state officials want to keep her confined, they have to prove it in court and a judge has to order it.

Napolitano pointed out that Gov. Christie had to order Hickox released because he would have lost in court.

"We start with the principle that she's free. We all have the presumption of liberty in this country. ... If the government wants to confine you, you do not have to prove that you are worthy of freedom. The government has to prove you are worthy of confinement," he explained, adding that he understands the concerns of Hickox's neighbors.

Napolitano says the government must prove it has a "compelling interest" to keep Hickox under quarantine.
