Ricin Letter
Ricin letter sent to NYC Mayor Michael Bloomberg Twitter

A ricin-laced letter sent to New York City Mayor Michael Bloomberg has been revealed to contain an angry message threatening Bloomberg for his stance on gun control. Similar letters were also sent to President Obama and the headquarters of Bloomberg’s advocacy group Mayors Against Illegal Guns.

Previously, news outlets reported small pieces of the text in the Bloomberg ricin letter, but on Thursday, ABC anchor Aaron Katersky tweeted a photo of the letter in its entirety, with the full text clearly visible. The letter, postmarked from Louisiana, threatened that Bloomberg would have to risk being shot before he could "get" the senders guns.

The text of the ricin letter reads, in full:

"You will have to kill me and my family before you get my guns. Anyone wants to come to my house will be shot in the face. The right to bear arms is my constitutional God-given right and I will exercise that right 'til the day I die. What's in this letter is nothing compared to what I've got planned for you."

Bloomberg has stated that he does not feel threatened by the letters or their contents. He also promised that no matter what the letters said, he would not back down on efforts to increase gun-control in New York City. Bloomberg is head of the super PAC and advocacy group Mayors Against Illegal Guns.

"In terms of why they've done it, I don't know," he told the Associated Press on Wednesday. The letters "obviously referred to our anti-gun efforts, but there's 12,000 people that are going to get killed this year with guns and 19,000 that are going to commit suicide with guns, and we're not going to walk away from those efforts.”

The postal service union said in a memo to members Tuesday that the U.S. Postal Service was “made aware” of the ricin letters on May 20. All three letters were postmarked from Shreveport, La.

“We have no reason to believe that any employees are at risk from handling the [Bloomberg] letter as it passed through the mail stream,” the memo said. “The substance involved was not in a form that could be inhaled or otherwise readily ingested. Public health experts do not believe that the material in these letters presented a health risk to anyone who came in contact with them.”

The FBI is currently investigating who may have sent the letters.
