As supercouple Jay-Z and Beyoncé prep for World Humanitarian Day ("I'm doing something good," Mrs. Carter tweets, "somewhere, for someone else. Join me!"), they're also getting slammed by South Floridian members of Congress Ileana Ros-Lehtinen and Mario Diaz-Balart for helping to "fund the machinery of oppression."

How exactly? Spending all them tourist dollas in Castro's Cuba.

UPDATE Jay-Z and Beyonce's trip to Cuba was approved by U.S. Treasury as a "people-to-people" cultural visit.

UPDATE #2 Marco Rubio says Jay-Z and Beyonce are "tourists who have no interest in the Cuban people's freedom," demands the "Obama administration explain."

UPDATE #3 The Treasury Department has officially confirmed that Jay-Z and Beyonce's trip to Cuba was indeed "authorized."

UPDATE #4 Ros-Lehtinen still insists Jay-Z and Beyonce in Cuba "was a wedding anniversary vacation that was not even disguised as a cultural program."

UPDATE #5 Jay-Z's finally responded to his Cuba haters with a new track called "Open Letter" and words like, "Obama said, 'Chill, you gon get me impeached.'"

UPDATE #6 Pitbull has dropped a rap response to Jay-Z and Beyonce's Cuba visit, offering to pay for the trip.

UPDATE #7 Problem Kids have released "Useful Idiot" about Jay-Z: "The real cuba is not what he portrayed"

UPDATE #8 Obama has commented on Jay-Z and Beyonce in Cuba, saying: ""This is not something the White House was involved with. We've got better things to do."

From the moment Hova and Bey were spotted in Havana last week, it was inevitable that a Republican backlash was coming down.

A commie country, Cuba has been embargoed for six decades. And it is forbidden territory for American visitors, unless granted special permission from the U.S. government.

So as our sister blog Riptide pointed out: "No one is really sure how legal [Jay-Z and Beyoncé's] trip is. The embargo forbids Americans from traveling to Cuba for tourism reasons, but exceptions are made for people traveling for academic, journalistic, religious and cultural reasons."

Of course, though, the Carters are quite cozy with the Obamas. (As Barack says, "We've got a little bond there.") So presumably, their Cuba request could've been hella fast-tracked.

But Ros-Lehtinen and Diaz-Balart want proof.

"Cuba's tourism industry is wholly state-controlled," the pair writes in a letter to the Prez and the U.S. Treasury Department, questioning the legality of Hova and Bey's anniversary vacay on the island.

"U.S. dollars spent on Cuban tourism," the members of Congress bluntly state, "directly fund the machinery of oppression that brutally represses the Cuban people."

Now... Who's ready for World Humanitarian Day?
