Thousands of foreign fighters and funds from Hezbollah are fueling troops in Syria and propping up the regime of Bashar Assad, Rep. Mike Rogers said on CBS's Face the Nation Sunday.
"They want to get more sophisticated chemical weapons," Rogers said. "This is as bad a situation as I've seen."
Rogers said that the U.S. could play a "coach" rather than "sheriff" role to stabilize the region.
President Obama Sunday signaled support for recent Israeli air force strikes inside Syria, saying Israel has a "justifiable" interest in preventing weapons from Iran reaching Syrian forces.
Obama had previously said that the use of chemical weapons against Syrian civilians would constitute a "red line" that would force his administration to consider a different approach. Now that there are reports that chemical weapons may have in fact been used, it is unclear how the Obama administration will move forward.
