Governor Paul LePage of Maine has returned to his State House office to conduct business. The governor was back at his desk Wednesday, nearly a week after he vacated it following a dispute over whether a television should be allowed in the hall outside his office. Legislative leaders said the television, which carried messages giving the governor’s views on the proposed state budget and other issues, violated rules of State House decorum. Now, the television has been removed to an area inside the governor’s office, although it is still visible from the Hall of Flags. It shows a new message, including ‘‘No New Taxes.’’ No complaints have been reported.
