In a developing story Wednesday morning, a letter addressed to President Obama tested positive for the deadly ricin poison. And Fox News is now reporting a “suspicious letter” sent to the offices of U.S. Sen. Jeff Flake (R, Ariz.).
FBI officials said the letter to Obama was sent from the same person who sent a ricin poison laced letter to U.S. Sen. Roger Wicker, (R, Miss.), NBC News reported.
Both letters were intercepted from separate government mail screening facilities on Tuesday and are now on the way to laboratories for a “full analysis,” the article said.
Though FBI officials told NBC they do not believe the poisoned letters were related to the bombings at the Boston Marathon Monday, Press Secretary Jay Carney told reporters Wednesday the FBI isn’t ruling out that possibility at this time.
“Federal officials told NBC News that they believe they know who sent the letters, but no arrest was made because authorities were waiting for further test results,” according to the article.
Fox News received an FBI bulletin that said both letters included the phrase: ‘To see a wrong and not expose it, is to become a silent partner to its continuance.’ Both were signed, ‘I am KC and I approve this message.’”
When notified of the situation, U.S. Sen. Claire McCaskill “said that the person who sent Wicker the letter writes often to elected officials,” the Associated Press reported.
Fans of the show “Breaking Bad” will know ricin is found naturally in castor beans and just the tiniest amount inhaled or ingested can be deadly. There is no antidote to the ricin posion, according to the Centers for Disease Control and Prevention.
