McCain, the ranking member of the Senate Armed Services Committee, has slammed the Obama administration's handling of the Syrian crisis and called for the United States to arm the rebels fighting against President Bashar al-Assad.  

The Zaatari refugee camp is located close to the border between Jordan and Syria, and many Syrians have entered the camp to flee the violence in their home country, according to the BBC.

On Friday McCain tweeted that he met with military officials and service members in Afghanistan.

McCain and Sen. Joe Lieberman (I-Conn.) visited a Syrian refugee camp on the Turkey-Syria border this spring. During the trip, the two said the international community is "failing the people of Syria" by only providing humanitarian aid and urged the U.S. to arm the rebels battling against Assad's forces.
