WASHINGTON - The White House said on Tuesday it does not expect a formal announcement of when the United States and Cuba will re-open embassies in their respective countries before a hemispheric summit this week. 'I would not anticipate that we would be formalizing the opening of embassies at the summit,' Deputy National Security Adviser Ben Rhodes said at a briefing before President Barack Obama's travel to Jamaica and Panama. Rhodes said a State Department review on whether to remove Cuba from the US list of terrorism-sponsoring nations is near completion but he cannot predict when it will make a recommendation.
