Letter addressed to White House tests positive for poison
WASHINGTON — A letter addressed to President Donald Trump tested positive for the poison ricin earlier this week.
Officials intercepted the letter before it could reach the White House.
The FBI said Saturday that they are investigating “a suspicious letter received at a U.S. government mail facility” alongside their partners at the U.S. Secret Service and the U.S. Postal Inspection Service. Law enforcement officials said a letter was detected at an off-site facility that screens mail addressed to the White House.
“At this time, there is no known threat to public safety,” said the FBI in a statement.
The letter tested positive for the poison in both a field test and a laboratory test. The FBI, Secret Service and the Postal Inspection Service are trying to determine where the letter came from.
One official said other letters that have also tested positive for ricin were discovered in different facilities, however it is unclear how many additional poisoned letters were found, most of them seem to be addressed to prisons, and only one was apparently addressed to a political figure.
Ricin is highly toxic that could cause nausea, vomiting, and internal bleeding of the stomach and intestines. Depending on the severity of the exposure, it can also cause failure of the liver, spleen and kidneys, and death by the collapse of the circulatory system.
