U.S. Senator Rubio says release of Gross 'sets a dangerous precedent'

WASHINGTON (Reuters) - U.S. Senator Marco Rubio of Florida said the release of U.S. aid worker Alan Gross from Cuba "sets a dangerous precedent" that "puts a price on Americans abroad." Speaking on Fox News, Rubio, a Cuban-American Republican and potential 2016 White House contender, said he did not believe the U.S. Congress would support lifting the embargo on Cuba.
