RCMP PROBE LETTER WITH RICIN BOUND FOR WHITE HOUSE

Canadian law enforcement has been called in to help the FBI investigate after American authorities found that an envelope addressed to the White House contained the poison ricin. “Initial information from the investigation suggests that the letter originated in Canada,” RCMP spokesman Dan Brien said in an email on Saturday. The letter was intercepted at a government facility that screens mail addressed to the White House and President Donald Trump, an American law enforcement official told The Associated Press. In a statement, the FBI said there is “no known threat to public safety.” Brien said an analysis found that the letter contained ricin, a toxic substance found naturally in castor beans.
