A social media movement calls for the release of Oscar López Rivera on his 73rd birthday, Jan. 6. The online campaign, led by the National Boricua Human Rights Network, is targeting a million posts on Twitter for freeing the man who has already been imprisoned for 34 years.

According to a report from Latino Rebels, López Rivera was a Puerto Rican nationalist who campaigned hard for the independence of his country. Having served time already, the website urged people to join the social media movement by tweeting, using the hashtags # #RegaloPaOscarLibertad or #FreeOscarLopez, and tagging President Barack Obama and First Lady Michelle Obama.

A report from Workers.org revealed that the people of Puerto Rico are all united in demanding López's release with the governor even officially visiting the prisoner.

34 Mujeres x Oscar, a group that holds a rally for the Puerto Rican's freedom every last Sunday of the month, is also entirely committed to the cause. Their rallies often last just 34 minutes long, a minute for each year López Rivera has been imprisoned. According to CBS New York, the group of women took to the streets last December and explained their call.

"His only crime was supporting the independence of Puerto Rico," Melissa Montero pointed out. ""We live in the United States, you know we talk about freedom of speech, we talk about human rights - but here in this own country we have human rights violations."

Not everyone was thrilled to see the demonstration in Times Square, but the member said, "We're a group of women that are extremely respectful, and we expect others to respect us as well."

According to Latino Rebels, López Rivera was charged and convicted back in 1981 for seditious conspiracy, use of force to commit robbery, interstate transportation of firearms and conspiracy to transport explosives with intent to destroy government property for his alleged involvement with the Fuerzas Armadas de Liberación Nacional (FALN).

He was given 55 years in federal prison, the CBS New York Report added. While it was a long list of charges, López Rivera wasn't charged with killing anyone. A few years later, 15 more years were added to his sentence when he was found and charged with conspiracy to escape prison.

López Rivera's release has been debated on for a long time and in 1999, former president Bill Clinton even offered clemency to Lopez Rivera and 15 other Puerto Rican nationalists. However, Lopez refused.
