No, it's called respecting people's privacy. Politicians are people too. It is never ever acceptable to confront a politician in a bathroom. End of story.
I am very curious what Spanberger thinks of the redistricting commission in Virginia. Probably very unhappy because Dems could have easily shored her up. Who knows how the commission will draw the district but it could be unfriendly to her.
If she loses, she probably joins the Biden admin in a national security position.
She would have been an interesting gubernatorial candidate.
