This was written on his website. Note the red box.
It was saved by us good guys.
Chuckie changed the written stuff later. This was not a slip of his tongue nor a verbal modification of his written, prepared text.
Chuck read what he wrote :

What’s written in the red box isn’t what he said. The written version has “...the lack of protection for these tribes”, which is fairly passive. In the spoken version Schumer explicitly calls out the troops as having failed to protect the Sunnis.
