Letter containing poison addressed to Trump at White House

Letter containing poison addressed to Trump at White House

A package containing the deadly poison ricin address to President Donald Trump at the White House was intercepted this week, and the origin of the mail attack is being investigated, officials say.

The White House and U.S. Secret Service declined to comment.

The RCMP said Saturday it is working with the FBI after federal USA officials intercepted an envelope addressed to the White House that contained the poison ricin. CNN reports that two tests were done to confirm the presence of ricin.

The FBI said in a statement agents were investigating "a suspicious letter received at a United States government mail facility" and there was "no known threat to public safety".

Ricin is naturally found in castor beans, but it can be made into a poison from the waste "mash" produced when castor oil is made. Law enforcement from the Secret Service and Federal Bureau of Investigation confirmed that the substance in the package was the highly potent poison, ricin. There is no known antidote. If a person is exposed to ricin, death can take place within 36 to 72 hours, depending on the dose received, according to the US Centers for Disease Control and Prevention (CDC).

The incident is now under investigation, the Times said, and investigators are looking into whether more such envelopes have been mailed.

In May 2014, a MS man, James Everett Dutschke, was sentenced to 25 years in prison after pleading guilty to sending letters with the deadly substance to Obama, as well as a senator and a state judge.

In 2014, "The Walking Dead" actress Shannon Richardson was convicted of sending envelopes that contained highly toxic ricin to then-President Barack Obama and then-New York City Mayor Michael Bloomberg.
