Sanders was asked to leave the Red Hen restaurant in Lexington, Virginia, on Friday night. She confirmed the incident with her Saturday tweet.
Sanders’ tweet from her official @PressSec account noted that the restaurant owner’s actions “say far more about her than about me.”
Shaub later tweeted that Sanders used her official government account "to condemn a private business for personal reasons."
Former White House lawyer Ian Bassin said on Twitter that Sanders' tweet would have been acceptable under her personal account, but not from her White House one.
“I think there’d have to be some argument that it was in service of the American people and not me personally. But read Sanders’ tweet. It doesn’t claim to be about public; the whole thing is ‘I’ and ‘me.’” Reads like it’s personal, which is fine from a personal account, not WH one,”” Bassin tweeted.
Red Hen owner Stephanie Wilkinson said she personally asked Sanders to leave the restaurant.
"I'm not a huge fan of confrontation," Red Hen owner Stephanie Wilkinson told The Washington Post. "I have a business, and I want the business to thrive. This feels like the moment in our democracy when people have to make uncomfortable actions and decisions to uphold their morals."
When asked to leave, Sanders' response was immediate, Wilkinson told the Post. "'That's fine. I'll go.' "
The Red Hen's Facebook and Yelp pages were bombarded with reviews from people from both sides.
While some praised the restaurant, many others said the owner was being “intolerant.”
This comes after Homeland Security Secretary Kirstjen Nielsen bolted from a Washington, D.C. Mexican restaurant after protesters confronted her at her table -- with the blessing of the manager.
