HARRISBURG, Pa. (AP) — Two news organizations are reporting that the Pennsylvania Senate is hiding thousands of detailed explanations about its expenses from official records it provided under public records requests. The Caucus and Spotlight PA news organizations reported that Senate officials edited out the explanations, making it appear as though they didn’t exist. Lawyers who specialize in public records access cases in Pennsylvania say public officials aren’t allowed to erase parts of public records. They say public officials must justify why they choose to redact or not release certain pieces of information. Pennsylvania’s Legislature is one of the nation’s largest and most expensive.
