That’s a great question.

This past April, authorities intercepted ricin-laced letters sent to Sen. Roger Wicker and President Obama. And this morning, media report that yet another letter sent to President Obama may be positive for ricin.

Just yesterday, we learned that letters mailed last week to Michael Bloomberg and his gun control group, Mayors Against Illegal Guns, tested positive for the poison.

Right on cue, many lefties are crawling over themselves to blame gun rights activists:

Pathetic. Terrorism is terrorism. And Second Amendment supporters do not support it.
