This is not reported in the US media: claims by Syrian armed groups

Ever since Obama declared his "red line" a year ago, Syrian armed groups make almost weekly or semi-weekly claims about alleged use of chemical weapons against them.  And they also upload videos in every case, and they get aired on Qatari and Saudi TV stations.  Somebody should investigate videos of past claims and compare them, unless the US would claim that chemical weapons are used once or twice a week by the regime.
