Clooney attacks O'Reilly over telethon criticism

George Clooney has gone on the offensive with American news man Bill O'Reilly again, for attacking celebrity charity efforts.

Outspoken Fox news anchor O'Reilly lashed out at Clooney, among others, when the movie star helped organised a telethon in the days after the 9/11 tragedy - and now he's on the attack again.
