As the Trump administration imposes deep cuts on foreign aid and renewable energy programs, the World Bank, one of the most important financiers of energy projects in developing countries, is facing doubts over whether its biggest shareholder, the United States, will stay on board.

While the Trump administration has voiced neither support nor antipathy for the bank, it has issued an executive order promising a review of U.S. involvement in all international organizations. And Project 2025, the right-wing blueprint for overhauling the federal government, has pressed for withdrawal from the World Bank.

If the United States were to withdraw, the bank would lose its triple-A credit rating, two credit-rating companies warned in recent weeks. That could significantly reduce its ability to borrow money. Roughly 18 percent of the bank’s funding comes from the United States.

In an interview, Ajay Banga,9x999 slots the bank’s president, said his institution was fundamentally different from the aid agencies, such as U.S.A.I.D., that the Trump administration has been cutting. And he used some of the administration’s own talking points to argue the case: Investment in natural gas and nuclear power is good, he said, and the development projects funded by the bank can help prevent migration.

He also said that the bank makes money and shouldn’t be seen as charity from U.S. taxpayers.

“The World Bank is profitable,” he said, noting that it more than covers its own administrative costs even if most of its projects are designed to yield slim returns. “It’s not as though we take money every year from taxpayers to subsidize us and our salaries.”

The concern about the bank’s future is heightened as the second Trump administration doubles down on its repudiation of climate projects and promotes an accelerated expansion of U.S. oil and gas projects.

Now, one of these groups — the 65 Project — is taking a more proactive approach. Starting on Thursday, the group’s organizers are planning to run advertisements in legal journals published in swing states, reminding lawyers that they are ethically barred from bringing false claims on behalf of any client.
