Meanwhile, investigators are looking into the possibility that the package addressed to Trump came from Canada.

In a statement to CNN, Mary-Liz Power, chief spokeswoman for Canada’s Minister of Public Safety Bill Blair, said, “We are aware of the concerning reports of packages containing ricin directed toward US federal government sites. Canadian law enforcement is working closely with their US counterparts. As this is an active investigation we cannot comment further.”

Besides, the Federal Bureau of Investigation (FBI) and Secret Service are probing the matter. “The FBI and our US Secret Service and US Postal Inspection Service partners are investigating a suspicious letter received at a US government mail facility. At this time, there is no known threat to public safety,” the FBI’s Washington field office said in a statement.
