A package containing the poison ricin and addressed to President Donald Trump was intercepted by law enforcement earlier this week, according to two law enforcement officials.
Two tests were done to confirm the presence of ricin. All mail for the White House is sorted and screened at an offsite facility before reaching the White House.
A US law enforcement official told CNN that investigators are looking into the possibility the ricin package sent to Trump came from Canada.
Mary-Liz Power, chief spokeswoman for Canada’s Minister of Public Safety Bill Blair, said in a statement, “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.”
