The father of the lone soldier accused of turning over massive cache of U.S. secrets to WikiLeaks sometimes refuses to acknowledge to strangers that his son is actually Pfc. Bradley Manning, according to an interview he gave ABC News.

Asked what he would say to his son if he admits guilt, Manning’s father responded: “‘You stupid eff’in idiot. Why would you do something like that?’ And probably more words after that. I’d probably be openly embarrassed at the way I’d been holding up, thinking he’s innocent — and embarrassed that he’d done such a thing.”

Manning faces 22 different charges stemming from his alleged release of secret U.S. State Dept. and military documents. If found guilty, he could be sentenced to death, or life in prison.
