During my time in Havana, I made contact with several members of what is often called Cuba’s “critical left,” a term used to refer to left-wing activists, journalists, intellectuals, and everyday people who are critical of either certain policies of the PCC or broader systemic issues in the party bureaucracy. I organized three meetings, two with independent journalist Maykel Vivero and one with members of the leftist La Tizza collective. I also spoke to and attempted to meet with Marxist writer Frank Garcia Hernandez but could not arrange it while I was in Havana.

On Maykel Vivero:

He is one of the few journalists who cover the persecution of the San Isidro Movement and its leader Luis Manuel Otero Alcántara. In his journalistic work, he thinks it’s very important to provide the most complete information possible without getting carried away by personal feelings.

On Luis Manuel Otero Alcántara:

State television revealed a document indicating San Isidro leader Luis Manuel Otero Alcántara receives monthly $1,000 payments from the National Democratic Institute, which is funded by USAID and NED.

edit:

The small San Isidro Movement in question campaigned for the re-election of Donald Trump in October, speaking to a South Florida-based audience, while applauding the damage being done to Cuba by the U.S. blockade, while asking for additional sanctions. Images have earlier circulated of the main leader of the San Isidro group, Luis Manuel Otero Alcántara, with the Charge d’Affaires of the U.S. embassy in Havana. Another member, Omara Ruiz Urquiola, also paid a visit to the diplomat; and Carlos Manuel Álvarez, who resides in Mexico and is linked to U.S. special services, through the CIA front National Endowment for Democracy (NED), arrived at the headquarters of the San Isidro Movement last Tuesday, November 24.

They have advocated for the tightening of the blockade and the cutting off of remittances and their end goal is an overthrow of the revolutionary Cuban government.
