An Idaho lawmaker who shared the personal information of a 19-year-old student intern online after the teenager accused another lawmaker of rape was formally censured by the Idaho House of Representatives on Monday.

The representative, Priscilla Giddings, a Republican from White Bird, Idaho, was stripped of a committee assignment because she had shared an article that included the intern’s personal details on Facebook and in a newsletter with her supporters.

Ms. Giddings, who is seeking the Republican nomination for lieutenant governor, shared the information after the intern in March accused State Representative Aaron von Ehlinger of sexual assault.
