Nebraska Gov. Pete Ricketts is self-isolating from the public after he was exposed to someone over the weekend who tested positive for the coronavirus on Monday. Ricketts says he was near the person for longer than 15 minutes on Saturday. He had been scheduled Monday to participate in the Governor’s Annual Wellness Walk around the Capitol to promote fitness, but spoke to reporters instead through a video-conferencing link. Ricketts says his contact with the person who tested positive for the virus was for business and not a social gathering, but he didn't identify the person.
