On 20 September, local authorities detained a woman suspected of sending a deadly poison in an envelope. The letter was intercepted at a government facility that screens mail addressed to the White House and President Donald Trump, and a preliminary investigation showed that it tested positive for ricin.
The suspect was detained when trying to enter the United States from Canada, a federal law enforcement official told NBC.
In 2018, a former US Navy officer reportedly sent two pieces of mail with castor seeds to then-Defence Secretary James Mattis and then-Chief of Naval Operations Adm. John Richardson. Similar packages were allegedly also sent to the White House and the office of US Senator Ted Cruz.
