Hickox complained about her treatment in New Jersey after she became the first person forced into the state's mandatory quarantine, announced Friday by Christie for people arriving at Newark Liberty International Airport from three West African countries.
"We are pleased that the state of New Jersey has decided to release Kaci. They had no justification to confine her," said Norman Siegel, the prominent New York civil rights attorney Hickox hired while she was quarantined. He said that she has not ruled out legal action.
"We are figuring out how to amplify Kaci's voice on this issue," Siegel said. "We have to figure out if that is through the courts of law or through the court of public opinion."
Speaking at a campaign event for Florida Gov. Rick Scott in Wellington, Florida, on Monday morning, Christie said when Hickox "has time to reflect, she'll understand" the quarantine and that he is happy to send her home.
Maine Gov. Paul R. LePage said that the state will work with health care workers who treated Ebola patients in West Africa to establish in-home quarantine protocols.
Christie and New York Gov. Andrew Cuomo jointly announced the quarantine policy on Friday. But over the weekend, the Obama administration condemned the mandatory quarantines. Late Sunday night, Cuomo and Christie stressed separately that the policies allowed for home confinement for medical workers who have had contact with Ebola patients if the workers show no symptoms.
Under New Jersey's protocol, state residents who had come into contact with someone with Ebola would be subject to a mandatory 21-day quarantine at home, even if they had no symptoms. Non-residents who landed in the state would be taken home if feasible or otherwise quarantined in New Jersey.
In a telephone interview Saturday with CNN, Hickox said she did not initially have a shower, flushable toilet, television or reading material in the special tent she was in at University Hospital in Newark.
Hickox did not immediately return a phone call or email seeking comment from The Associated Press.
Christie said Monday that his priority is protecting the health of people in his state.
"I understand that she didn't want to be there, she made that very clear from the beginning," Christie said. "But my obligation is to all the people of New Jersey and we're just going to continue to do that."
