Lethal Weapon star Danny Glover and Sean Penn are among the stars who have petitioned U.S. President GEORGE W. Bush in a bid to bring U.S. and Cuban artists closer together. The duo is among the artists, scholars and performers who sent a letter to Bush on Tuesday (27Nov07), asking the President to consider lifting travel restrictions on U.S. and Cuban artists. In the letter, the collective artists write, "We are writing you as representatives of the cultural sphere in the U.S. We write you as American citizens. We write to express our dismay at your administration's continuing hostility towards Cuba." America and Cuba have had tense relations since the 1959 Cuban revolution and the U.S. cut off the Caribbean island in 1962 when politicians enforced a trade embargo in 1962, which is still in effect today.
