The shipment came from Canada and was discovered by security forces at the White House mail controls
Security forces intercepted a package addressed to the president of the United States, Donald Trump, which contained traces of ricin, a powerful poison that can be deadly. The FBI and Secret Service (the presidential police) confirmed in a statement the find. Sources cited by The Wall Street Journal and The Washington Post They assured that the shipment comes from Canada. There were no further details on Saturday noon.
Ricin is a poison derived from castor beans that can be presented in powder, in balls or dissolved in water, depending on the US Center for Disease Control page. Its effects vary depending on whether it has been inhaled, ingested, or injected. Symptoms are seen within hours of exposure. It affects the lungs, liver and kidneys and can end up causing death within 72 hours. Experiments with ricin as a biological weapon date back to the 1940s.
In the last decade there have been several attempts at terrorist attacks with envelopes containing ricin. In 2013, the White House intercepted two ricin letters addressed to then-President Barack Obama. Another similar attack was directed against the mayor of New York, billionaire Michael Bloomberg.
