WASHINGTON (Reuters) – Authorities are investigating a letter addressed to President Barack Obama after the contents preliminarily tested positive for the deadly poison ricin, the second report of such a letter in two days.
The FBI said the envelope was received at a mail screening facility outside the White House and was immediately quarantined.
The mailings to Obama and Wicker were related, based on the postmarks and the identical language of the enclosed letters, according to an FBI operations bulletin reviewed by Reuters.
The letters included the phrase, “To see a wrong and not expose it, is to become a silent partner to its continuance,” and were signed, “I am KC and I approve this message.”
The envelopes both bore postmarks from Memphis, Tennessee and were dated April 8.
