Hollen, D-Md. are calling on President Biden to ease restrictions on Cuba that impact the island’s private sector.

In a letter sent Wednesday, the lawmakers urged the president to boost the economic exchange between U.S. and Cuban entrepreneurs by taking “risk-based, targeted efforts, including narrow changes to U.S. licensing and regulations.”

The aim is to promote the growth of Cuba’s small and medium-sized private enterprises, give them greater access to U.S. financial services and increase U.S. exports to the island.
