WASHINGTON โ Federal officials intercepted an envelope addressed to the White House that contained the poison ricin, a U.S. law enforcement official told The Associated Press on Saturday. A preliminary investigation indicated it tested positive for ricin, a poison found naturally in castor beans, the U.S. official said. The U.S. official was not authorized to discuss the ongoing investigation publicly and spoke on condition of anonymity. Federal investigators were working to determine where the enveloped originated and who mailed it. In 2014, a Mississippi man was sentenced to 25 years in prison after sending letters dusted with ricin to President Barack Obama and other officials.
