The mother of Sean Smith - one of the four Americans killed in Libya not as the result of a spontaneous demonstration that was not in response to an "outrageous movie" - found the President's "bit" with Jon Stewart demeaning to her son:
During an interview shown on Comedy Central, Obama responded to a question about his administration's confused communication after the assault by saying: 'If four Americans get killed, it’s not optimal.'
Speaking exclusively to MailOnline today, Pat Smith, whose son Sean died in the raid, said: 'It was a disrespectful thing to say and I don't think it's right.
'How can you say somebody being killed is not very optimal? I don't think the President has the right idea of the English language.'
