Earlier, President Barack Obama confirmed the department's recommendation was ready, but said he would not reveal what it was before heading to the Summit of the Americas in Panama.
"The State Department's recommendation to remove Cuba from the list of state sponsors of terrorism, the result of a months-long technical review, is an important step forward in our efforts to forge a more fruitful relationship with Cuba," Senator Ben Cardin said yesterday.
Cardin's spokeswoman Sue Walitsky confirmed to AFP that Cardin had been informed of the State Department decision, but added: "I wouldn't use the term 'official' at this point in time."
Obama is to meet Cuba's President Raoul Castro during the two day summit, the next step as the countries' gingerly negotiate revived diplomatic ties and a loosening of the US trade embargo.
"It is my expectation that this announcement will clear the way for the United States and Cuba to re-establish diplomatic relations and strengthen people-to-people ties between our two countries," Cardin said, even as Obama flew to Panama.
Cuba's place on the US terror blacklist, which it received during the Cold War for sponsoring leftist movements in several conflicts, has been a sticking point in negotiations on closer ties.
