Two tests were performed to confirm the presence of ricin. All mail for the White House is sorted and verified in an off-site facility before it reaches the White House.
A U.S. law enforcement officer told CNN that investigators are investigating the possibility that the package of ricin sent to Trump was from Canada.
Mary-Liz Power, chief spokeswoman for Canada’s Minister of Public Security, Bill Blair, said in a statement: “We are aware of reports of packages of ricin being sent to federal government locations. Canadian law enforcement agencies are working closely with theirs US colleagues together As this is an active investigation, we cannot comment further. “
The FBI and the Secret Service are investigating the matter.
Ricin is a highly toxic compound extracted from castor beans that has been used in terrorist attacks. It can be used in powder, pellet, mist, or acid form. If ingested, it causes nausea, vomiting and internal bleeding of the stomach and intestines, followed by failure of the liver, spleen and kidneys and death from breakdown of the circulatory system.
“The FBI and our US Intelligence and Postal Inspection partners are investigating a suspicious letter that has arrived at a US government mailroom. There are currently no known threats to public safety,”
CNN has asked the Secret Service for a comment.
