NBC said Tuesday that Snyderman and her crew are taking their temperatures regularly and remain healthy. The team was reporting in Liberia alongside cameraman Ashoka Mukpo, who tested positive for the deadly disease and is now being treated in Nebraska.
Snyderman confirmed the violation, but neither she nor NBC representatives would give details.
The local news website Planet Princeton reported that Snyderman and others drove for takeout food last week.
After the report, New Jersey health authorities ordered Snyderman and her crew to remain quarantined until after 21 days had passed since their potential exposure to the virus.
"As a health professional I know that we have no symptoms and pose no risk to the public, but I am deeply sorry for the concerns this episode caused," Snyderman said. She would not say whether or not she had violated the voluntary quarantine.
NBC, citing privacy concerns, also would not say how many of its employees are being quarantined.
