President Trump says he’s reluctant to lift shipping restrictions to get more aid to hurricane-ravaged Puerto Rico — because mariners don’t want him to.

“We’re thinking about that,” Trump said Wednesday when asked about lifting the Jones Act, which prohibits foreign ships from moving goods between US ports.

“But we have a lot of shippers and a lot of people that work in the shipping industry that don’t want the Jones Act lifted, and we have a lot of ships out there right now.”

The law was lifted for both Florida and Texas after they were hit with hurricanes earlier this month, but the government on Monday denied a similar reprieve for Puerto Rico, where millions are without fuel and drinking water.

Puerto Rican pols and some mainland lawmakers argue the restrictions are stemming the flow of aid to the island, and forcing residents to pay a huge premium on goods.

But the Department of Homeland Security has argued the US territory doesn’t have the infrastructure to dock more boats — and those in the industry say it will rob US citizens of work.

“[The waiver] would take American first responders out of the loop and replace them with Filipino or Russian or Chinese crews,” Michael Roberts, a senior vice president at Florida’s Crowley Maritime Inc., told the Wall Street Journal.

“Doing that at a time when many US mariners in this region have had their homes damaged, their lives uprooted and now they need to work, to take that away is not something you want to do.”
