This November, Massachusetts voters may be asked to approve a state income tax cut from 5% to 4%. Supporters say the tax cut would give the state a competitive edge, boost the economy and improve affordability. But opponents, including four New Bedford lawmakers, argue it could put public programs at risk and threaten an already strained state budget.

The question has put business leaders at odds with union leaders and the state Legislature.

House Speaker Ron Mariano has said that raising other taxes is a possibility if voters approve the ballot question in November, but he recently indicated that he’s open to negotiating a compromise with the committee that organized the ballot question. The committee said it’s open to the idea.

Proponents point to outmigration, affordability challenges

FRANKFURT, Germany (AP) — The U.S. Navy is imposing a sea blockade against Iran — the latest escalation in the war that has seen the flow of key energy supplies choked off at the Strait of Hormuz.

The blockade that started Monday “has been fully implemented,” according to a statement Wednesday from Adm. Brad Cooper, commander of the U.S. Central Command. In the blockade's first 36 hours, “U.S. forces have completely halted economic trade going in and out of Iran by sea,” he said. The blockade could put serious pressure on the Iranian economy.

Shipping data firms say Iran-linked or sanctioned vessels have left the Gulf through the Strait — but then stopped or turned around. An uncertain and risky shipping situation is being complicated by jamming or faking of location systems.

Here are key things to know about the blockade and the situation at the Strait of Hormuz.
