CBRN event in United States of America on Wed 3rd October 2018

Two envelopes suspected of containing ricin poison, one addressed to Defense Secretary James Mattis, were identified in the Pentagon's Central Processing Center, according to a U.S. official. Later on Monday, the Secret Service reported it had also intercepted a suspicious envelope addressed to President Donald Trump, though that envelope was not received, nor did it enter the White House. The envelopes found at the Pentagon's mail center were addressed to Mattis and Chief of Naval Operations Adm. John Richardson, the official said. Those pieces of mail, flagged as part of the Pentagon's normal processing procedures, are being examined to determine whether they test positive for the deadly poison, the FBI said in a statement. The Secret Service said it's also cooperating with law enforcement to fully investigate the suspicious envelope addressed to the president. "Further, all threats directed towards the President, or any Secret Service protectee, are treated seriously and fully investigated," the Secret Service said in a statement.
