SAN JUAN, Puerto Rico (AP) Hundreds of Puerto Ricans are marching through the island's capital to demand the release of a 70-year-old Puerto Rican nationalist who belonged to a militant group that sought independence for the U.S. territory decades ago.

Oscar Lopez is scheduled to be released from a federal prison in Indiana in June 2023. He was sentenced to 55 years in prison after a 1981 conviction on charges including seditious conspiracy, use of force to commit robbery and interstate transportation of firearms. He received another 15 years in 1988 after being convicted of conspiring to escape from prison.

Former President Bill Clinton offered him clemency in 1999, but he didn't sign the deal in part because it did not include two comrades who have since been released.

The march for Lopez was Saturday.
