The Trump administration issued a stop-work order, over national security concerns, on a nearly completed offshore wind project for Massachusetts and Rhode Island.

Connecticut Gov. Ned Lamont is scheduled to go to State Pier in New London, Connecticut, on Monday, where components for the Revolution Wind project are kept before being taken out to sea. Rhode Island Gov. Dan McKee is headed to North Kingstown, Rhode Island, where the logistics and operations hub for the project is located.

The $4 billion offshore wind farm — nearly 80 percent complete — is a key part of Rhode Island’s workforce development and climate goals.
