New York Mayor Michael Bloomberg says a ricin-laced letter sent to him was "obviously" meant to show opposition to his lobbying for tighter gun ownership laws, but vowed to never "walk away."
Another suspicious letter addressed to the White House has been intercepted, the Secret Service said Thursday.
The letters "obviously referred to our anti-gun efforts," Bloomberg said at an event late Wednesday.
ABC television posted what it said was an exclusive picture of the letter sent to Bloomberg on its website. The stained, type-written letter, containing numerous spelling errors, reads:
"You will have to kill me and my family before you get my guns. Anyone wants to come to my house will get shot in the face.
"The right to bear arms is my constitutional God given right and I will excersice that right til the day I die. whats in this letter is nothing compared to what ive got planned for you."
