Last month President Obama called chemical weapons use by Syria a 'game changer,' but why do US interests change if chemical weapons are used?
According to the FBI, a Mississippi man was arrested for sending possibly poisonous letters to President Barack Obama and Senator Roger Wicker. There were other reports of mysterious packages in Senate office buildings and in senators' offices in their home states. Authorities are continuing to investigate the suspicious materials.
Preliminary tests indicate that letters sent to President Obama and to Sen. Roger Wicker (R) of Mississippi were laced with the potentially deadly poison ricin. They were postmarked Memphis, Tenn.
