The mother of James Foley -- an American journalist beheaded by ISIS militants -- said she is "embarrassed and appalled" by how the U.S. government dealt with her son's case, telling CNN that officials even suggested family members could be charged if they raised ransom to free him. "I think our efforts to get Jim freed were an annoyance" to the U.S. government, Diane Foley told CNN's Anderson Cooper in an interview that aired Thursday. "It didn't seem to be in (U.S.) strategic interest, if you will." Officials told Foley family members "not go to the media," and that the "government would not exchange prisoners,"  or carry out "military action" to try to rescue her son, according to Diane Foley.
