U.S. Senator John McCain said on Wednesday, two days after meeting with rebels in Syria, that he is confident the United States can send weapons to fighters in Syria without the risk they will fall into the wrong hands.

“We can identify who these people are. We can help the right people,” McCain said on CNN’s program “Anderson Cooper 360.” …

Critics of some lawmakers’ push to arm the rebels have expressed concerns that weapons could end up in the hands of militants who might eventually end up using them against the United States or its allies. …

“Every single day, more and more extremists flow in… “They’re flowing in all the time, these extremists. But they still do not make up a sizeable portion,” the Arizona senator said.
