I dont know how it relates to politics, if at all...
but...
"Ricin Letter Sent To Senator Who Ended Gun Control Filibuster; Second Letter Sent To Obama"
The gun legislation in the SENATE is officially dying today, correct? I don't want to speculate - that's what others are doing with such headlines, I'd guess.
They are seeking to imply maybe this is someone pissed off that the gun control bill is ending?
