The letter was intercepted at a government facility that screens mail addressed to the White House and President Donald Trump, the official said.

A preliminary investigation indicated it tested positive for ricin, a poison found naturally in castor beans, the official said.

The official was not authorized to discuss the ongoing investigation publicly and spoke on condition of anonymity.

In a statement, the FBI said agents were working to investigate “a suspicious letter received at a US government mail facility” and that there is “no known threat to public safety.” A Navy veteran was arrested in 2018 and confessed to sending envelopes to Trump and members of his administration that contained the substance from which ricin is derived.

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.
