FBI investigating poisoned letter sent to Donald Trump

Authorities in the US have thwarted an attempt to poison President Donald Trump.

The FBI has confirmed a letter addressed to the President tested positive for ricin last week.

“The FBI and our U.S. Secret Service and U.S. Postal Inspection Service partners are investigating a suspicious letter received at a U.S. government mail facility,” The FBI said in a statement.


“At this time, there is no known threat to public safety.”

Officials are now trying to determine where the package came from, with unconfirmed reports it was sent from Canada.

Ricin is a chemical poison found in castor beans and can be deadly if inhaled in even small doses.

Those who are exposed are likely to suffer breathing difficulty, fever, cough, nausea followed by a build up of fluid in the lungs, low blood pressure and respiratory failure.

More to come.
