Maine's governor said Wednesday he would seek legal authority to enforce a 21-day quarantine on a Maine nurse who has tested negative for Ebola after treating patients in West Africa and initially was isolated in a tent in New Jersey.

Gov. Paul LePage issued a statement after nurse Kaci Hickox said she would challenge the New England state's restrictions and would not follow guidelines to quarantine herself until Nov. 10 as demanded.

The controversy involving Hickox and officials in New Jersey and Maine highlighted the obstacles officials in U.S. states face as they try to guard against the spread of a disease that has triggered public alarm, without taking overzealous precautions.
