(CNN) – After spending four years imprisoned in Cuba, former American subcontractor Alan Gross has launched a hunger strike, trying to spur the U.S. and Cuba to resolve his case.
Gross, who was working for the U.S. Agency for International Development when he was arrested, was charged by a Cuban court in 2011 of being an American spy. USAID has said he was in the country working on a U.S. government project setting up satellite internet connections.
"He's a hostage. Under no normal law and order is providing internet access a crime, and therefore he's being held as a hostage," says Sen. Marco Rubio, R-Florida.
"The government of Cuba is trying to use him as a bargaining chip," and as a "pawn," Rubio said in an interview with CNN's "The Lead with Jake Tapper."
"He should be released immediately, he has done nothing wrong, he has committed no crimes," says Rubio.
