When a medical or other professional licensed in a state, they are required to obey state health laws! If a licensee disobeys and knowingly and publicly defies state law, their license is usually subject to Disciplinary Action and possible suspension/revocation.
Also, if the professional is licensed and is disciplined/suspended/revoked in one state, they are subject to Disciplinary Action in another state where their license allows them to practice.
Traci Hickox openly disobeying and defying a state health department mandate in Maine, should be walking on thin ice for licensure, if she still holds a current one. But maybe she doesn't need a state nursing license,
because she worked for the CDC as an Epidemic Intelligence Service Officer:
"Hickox is an official CDC Epidemic Intelligence Service (EIS) officer who performed work for the CDC in recent months.
Hickox was a Class of 2012 member of CDC’s two-year EIS officer training program, according to the official program for CDC’s 2014 EIS Conference (p. 98), which was held from April 28 to May 1, 2014. Hickox was featured in a photograph in the program.
Hickox was listed as an “EIS officer” for the CDC in program materials for a CDC course she taught in July 2014. She was specifically listed as an active “EIS officer” as recently as July 18, 2014, according to CDC documents.
Hickox was a presenter at the CDC conference this spring, according to the program’s list of presenters (p. 103).
Hickox taught an April 29 session called “Contact Investigation of Health Care Personnel Exposed to Maternal and Neonatal Tuberculosis—Clark County, Nevada, 2013″ at the conference (p. 3)…."
