Pictures that lie

George Bush did indeed need to go to the bathroom and wrote, "I think I may need a bathroom break. Is this possible?" on a note. But Reuters later admitted that it overexposed portions of the note so that the message stood out better.

Bush and Sen. John Kerry were subject to fraudulent photos during in the 2004 campaign. One fake photo circulated of Bush reading a book upside down. Another showed Kerry at a rally with actress Jane Fonda, but that particular encounter never happened.
