One of President Obama's last acts in office was to grant clemency to dozens of people, including Puerto Rican nationalist Oscar López Rivera.
On Wednesday, López Rivera was released from house arrest in Puerto Rico. The 74-year-old had been in custody for seditious conspiracy since 1981.
The clemency decision was controversial. "To his supporters, he is a freedom fighter for the cause of Puerto Rican independence. To others, he's a terrorist," NPR's Kelly McEvers noted at the time.
