Sociologist, poet, and blogger Guillermo Rebollo-Gil wrote an open letter on his blog to U.S. President Barack Obama in which he calls for the release of Oscar López Rivera, one of the longest-held political prisoners ever. The letter has quickly gone viral over the past two days.

Oscar López Rivera has been in prison for 32 years already, convicted of “seditious conspiracy”, even though it was never proven that he was involved in any violent activity, nor was he convicted of crimes that resulted in death or injury to anyone. After expressing great disillusionment with President Obama's administration, Rebollo-Gil writes:

Over the last three plus decades, five different Presidents have been sworn into office. I wonder if it would be possible for you to consider standing out amongst them. I wonder if you would be interested in imbuing your presidency with historical significance in the form of a direct action to assuage this injustice perpetrated by the American government. I wonder if you would be interested in affirming the fundamental American principle of freedom and grant a pardon to Mr. López Rivera. I really hope so. At all times.

Guillermo Rebollo-Gil's letter has been widely shared on social media and was republished on the online journal 80 grados [es].
