Marco Rubio, US Secretary of State, held a private 45-minute audience with Pope Leo XIV at the Holy See on Saturday 9 May 2026. The agenda covered Cuba and Venezuela. Rubio's central proposal, reported by CubaHeadlines, was to route US humanitarian aid to the island through the Catholic Church rather than through GAESA (Grupo de Administración Empresarial S.A., the Cuban military's economic conglomerate) or any other Cuban state channel.
The same day, Havana Cathedral held a state-level thanksgiving mass marking the first anniversary of Leo XIV's pontificate. Vice President Salvador Valdés Mesa, Foreign Minister Bruno Rodríguez Parrilla and Caridad Diego Bello, head of the Office for Religious Affairs, attended. The Apostolic Nuncio described the relationship as "90 years of unbroken diplomatic relations". Pope Leo XIV, an Augustinian, visited Cuba three times in his pre-pontifical career, in 2008, 2011 and 2019, giving the Holy See institutional standing inside Cuban Catholic infrastructure that the State Department does not have.
The 9 May meeting reverses Lowdown's prior reading. The Vatican channel had been characterised as superseded by the 10 April direct State Department aircraft track ; Rubio's audience layers it back over that track rather than displacing it. The Raúl Castro grandson back-channel remains active alongside. Three formal US tracks now run in parallel: bilateral handled by Cuban Deputy Foreign Minister Carlos Fernández de Cossío García del Toro, OFAC personal sanctions authored by Treasury Secretary Scott Bessent, and The Vatican humanitarian track Rubio is now personally bridging.
The 13 March prisoner-release announcement that Amnesty International later found contained zero prisoners of conscience flowed through the same Vatican channel before its 10 April supersession. Whether the Catholic-Church aid proposal moves from proposal to implementation depends on a public Holy See or State Department readout that has not yet appeared.
