U.S. leader President Barack Obama has distanced himself from the fuss surrounding his pals Jay Z and Beyonce's recent wedding anniversary trip to Cuba with his aides insisting he had no knowledge of the couple's vacation plans to Havana.

The pair hit the headlines earlier this month (Apr13) when photographs of the stars wandering around the streets of the Cuban capital began to circulate, prompting some politicians to ask if the trip had been authorised.

Americans need special permission to visit Cuba as tourists.

Jay Z's handlers responded to the controversy, insisting the trip was part of a cultural fact-finding initiative, and the rapper and his wife were not there simply as holiday-makers.

And he addressed the media furore himself on Thursday (11Apr13) in the lyrics of a new track, titled Open Letter, which was produced by Swizz Beatz and Timbaland, and released via his website.

Jay Z fires back at politicians, referencing their efforts to investigate his recent Cuba trip and even suggesting U.S. President Barack Obama is concerned about the controversy.

He raps, "I can turn Havana to Atlanta... Politicians never did s**t for me / except lie to me, distort history... They wanna give me jail time and a fine. Fine, let me commit a real crime. Obama said, 'Chill you're gonna to get me impeached'... You don't need this s**t anyway, chill with me on the beach'."

But it appears the rap has upset Obama's people and a spokesman for the President insists Obama "did not communicate with Jay Z over the trip."
