An original Norman Rockwell painting hangs behind Gov. Ned Lamont’s state Capitol office desk between the flags of the United States and Connecticut. The celebrated artwork depicts citizens assembled solemnly in front of a government hearing-room desk, and it’s called “The Right to Know.” But that title doesn’t fit in with what critics call a dismal track record by Lamont and his administration as to openness and prompt compliance with requests for public documents under the the state Freedom of Information Act. “I would say that certainly he’s developing a track record of somebody who sees FOI as more of a nuisance than a necessity,” said the president of the Connecticut Council on Freedom of Information, Mike Savino.
