Several news sources are confirming that a suspicious letter addressed to Mississippi Sen. Roger Wicker and intercepted has tested positive for the biotoxin ricin.
Some are noting that positive test results for ricin have proved to be false alarms more than once.
The news has just broken, so before anyone jumps to conclusions … sorry, too late.
