Florida Sen. Marco Rubio said Thursday he did not buy Mayor Bill de Blasio’s claim that he didn’t realize he was quoting a Marxist Cuban revolutionary.

Rubio was incredulous that the presidential hopeful appropriated one of Che Guevara’s most famous lines as he urged largely immigrant workers at Miami International Airport to unionize in protest of poor conditions and wages.

“De Blasio studied Latin American politics in college, was a very active supporter of the Sandinistas in #Nicaragua & even honeymooned in #Cuba in violation of U.S. law,” Rubio tweeted about the mayor’s history with the socialist nation.

Rubio then added sarcastically: “But he had NO IDEA he was quoting Che Guevara today. It was all just an incredible coincidence.”

De Blasio, fresh off a combative performance in Wednesday’s Democratic presidential debate, was attempting to give a dramatic speech when he uttered the Spanish phrase.

“The eyes of the world are on this airport, the eyes of the world are on Miami-Dade,” de Blasio told the workers, before ending with, “Hasta la victoria, siempre.”

The phrase translates to “Ever on to victory!” and was a mantra for Guevara, one of Fidel Castro’s top lieutenants.

The mayor claimed he was clueless about the origin of the phrase after making the boneheaded comment.

“That’s an honest mistake and I do apologize for it,” de Blasio said on CNN.

“I literally meant it as a Spanish phrase, you know, ‘that these folks were going to be victorious’, ‘hang onto victory’, that kind of thing.”

President Trump’s reelection campaign was quick to pounce on de Blasio’s gaffe.

“Maybe Miami, home to many Cuban and Venezuelan Americans, wasn’t the best place to pick to quote a murderous communist sociopath,” Trump campaign aide Tim Murtaugh said about the reference.

“People say candidates at the bottom of the pile have to do something to get attention. Not sure this is what they mean.”
