A 33-year-old York County native was sentenced Thursday morning to prison for aiding a group the United States designated as a terrorist organization.

Richard David Hupper, originally from York Township, was sentenced to 3 1/2 years in federal prison for aiding Hamas, a Palestinian military and political organization.

Hupper faced up to 15 years in prison. He admitted to giving about $20,000 to Hamas while working in Israel with the International Solidarity Movement, a non-governmental organization.
