In a column published Monday, former Cuban President Fidel Castro criticized Sen. Barack Obama’s (D-IL) May 23 speech in which he called for “justice for Cuba’s political prisoners, the rights of free speech, a free press and freedom of assembly” and “elections that are free and fair.” Obama said he would maintain the U.S. embargo on Cuba but open up contacts in other areas.

Speaking at a Cuban community center in Puerto Rico on Sunday, Sen. Hillary Clinton (D-NY) said she would “redouble our efforts to support civil society” in Cuba if elected.

The Libertarian Party nominated former Republican representative Bob Barr (AP) to be its presidential candidate on Sunday. Barr has spoken against possible war with Iran, and has been an adamant critic of the National Security Agency’s domestic eavesdropping efforts.
