WASHINGTON (WUSA9) -- At a vigil outside the White House on Tuesday supporters demanded that a Montgomery County man being held in Cuba be released.
Tuesday marks four years that Alan Gross has been held in a Cuban prison.
Gross was working in Cuba as part of a United States agency to increase internet access in the country's Jewish community.
The Cuban government arrested and sentenced Gross to 15 years in prison, accusing him of trying to undermine the regime by setting up unauthorized communications systems.
Tuesday Gross's wife read an open letter to President Obama.

The vigil was sponsored by the Jewish Community Relations Council of Greater Washington
