CNN had learned: early tests on envelope to senator show positive test for ricin poison. Further testing being done now

Senators were told it tested positive for RICIN – so don't tell me to calm down. RICIN IS NO JOKE

On ricin reports, I'd offer this as just a dollop of caution http://t.co/yoO6pfOdQV

There have been false positives before on ricin. From 2004: http://t.co/G60dq5ZNdh (via @johnjcook)

And, a roll of quarters in a Texas dorm room tested positive for ricin in 2006. http://t.co/i9et2mwCDJ Wasn't.

False-positives have followed previous #ricin scares — but CNN sez triple-test confirms poison in letter sent to Repub Sen. #Wicker

This news reminds me eerily of 9/11, then anthrax. Boston, then ricin letter. hmn.

Not to be a skeptic, but bombing the Boston Marathon + ricin being sent thru the mail seems awfully… Convenient. #justsaying

IF ricin letter is connected w/ Boston, it echoes Minnesota Patriots Council plotting of early 90s and 2011 Georgia plot. Both anti-tax/fed

Government does this as distraction. Terrorism exercise just before Boston bomb. Ricin just now in letter to Senate. Just before #CISPA vote

Probably right wing terror groups sent Ricin to all 16 "Traitor" Republican Senators to end gun control filibuster #Boston

— Jeff Gauvin (@JeffersonObama) April 16, 2013

The right wing paranoia about losing their assault guns is being played out in Boston and now these Ricin attacks on Capitol Hill.

— Jeff Gauvin (@JeffersonObama) April 16, 2013

This whole drama from Boston to Ricin is all about intimidation, retaliation, anger, hatred & pointing more to conservative groups
