Thousands of people are marching today in San Juan, Puerto Rico, in favor of the liberation of Oscar López Rivera, imprisoned in the United States 32 years ago on charges of “seditious conspiracy.” López Rivera, 70, is a fighter for the independence of Puerto Rico, a colony of the United States. Politicians, artists, and many people across different ideologies have united to ask the president of the United States, Barack Obama, to pardon López Rivera, who has been called the longest held political prisoner in the western hemisphere.
