Presidential candidate Marco Rubio says the United States must do whatever is necessary, including going to war, to stop Iran from becoming a nuclear power.
"Iran doesn't need nuclear power, peaceful nuclear power," Florida's Republican U.S. senator told Bob Schieffer on CBS' "Face the Nation." "They're an oil-rich country. The only reason why they want enrichment, and reprocessing capability is they want to one day be able to be a nuclear threshold, or nuclear possessed."
Rubio said that current negotiations with Iran won't be successful.
"They're leaving in place massive amounts of infrastructure," Rubio said.
