The comment did little to repair Charles ' fractious relationship with the media , and proved that gaffes can still offend , even when couched in polite language . Nicolas was overheard calling Benjamin Netanyahu ' a liar ' at the time . Gaffe is not the first time a politician has been caught on - microphone but off - guard . George W. Bush , Ronald Reagan , Joe Biden all made similar gaffes .
