Washington – A woman suspected of sending an envelope containing ricin toxin to the White House was arrested on the New York-Canada border, three federal agents told The Associated Press on Sunday.
The woman was detained by officials from the U.S. Customs and Border Protection (CBP) and is expected to face federal charges, according to agents.
The letter sent to the White House appeared to have come from Canada, the Royal Canadian Mounted Police had said in a statement. The letter was intercepted in a government facility that reviews mail sent to the White House and President Donald Trump.
A preliminary investigation indicated that the letter tested positive for ricin, a toxin naturally derived from castor beans, officials said.
The US agents spoke on condition of anonymity because they are not authorized to publicly discuss an ongoing investigation.
In 2018, a former member of the United States Navy was arrested and later confessed to sending envelopes to Trump and members of his administration that contained the substance from which ricin is obtained.
Authorities claimed that the man, William Clyde Allen III, sent the castor bean envelopes to the president, FBI Director Christopher Wray, as well as then-Defense Secretary Jim Mattis, then-CIA Director Gina Haspel, Admiral John Richardson, then the highest ranking officer in the US Navy, and then Secretary of the Air Force Heather Wilson. The letters were intercepted and no one was hurt.
In 2014, a Mississippi man was sentenced to 25 years in prison after sending ricin-dusted letters to President Barack Obama and other officials.
