Suspicious letters were also sent to the White House amid fears it contained deadly poison ricin.

Premier Brian Pallister now says he will defy Ottawa's carbon pricing plan by revamping his made-in-Manitoba green strategy to exclude a carbon tax.

Two letters sent to the Pentagon that were initially believed to contain the deadly poison ricin instead included castor seeds, from which the poison is derived.

Letters suspected of containing deadly poison that were sent to the White House and the Pentagon did not contain a finished form of ricin, officials said.

Ricin is back in the news with reports that envelopes suspected of containing the poison were sent to the White House and top defense officials.

The letter addressed to Defense Secretary James Mattis also contained a card with handwriting on it

There is no known antidote to the poison.

Two suspicious packages were discovered at a Pentagon mail facility Monday, the Associated Press reports. Then, this evening, the Secret Service announced that another envelope addressed to President Donald Trump was intercepted before it entered the White Ho…

Envelopes were sent to the Pentagon, White House and Sen. Cruz's office.

Ricin is a dangerous toxin that can cause serious illness or even death if humans come into contact with its purified form

Two pieces of mail that arrived at a Pentagon distribution center have tested positive for the poison ricin, defense officials said.

Packages with suspected ricin were sent to the Pentagon Tuesday

The Pentagon put its mail facility "under quarantine", while a hazardous materials response team was sent to Texas Senator Ted Cruz's campaign office

A Pentagon mail screening facility has found two envelopes suspected of containing the deadly poison ricin, one addressed to US Defence Secretary Jim Mattis.

The mail was addressed to Defense Secretary James Mattis and one other official.

Neither envelope entered the Pentagon; Authorities discovered the packages Monday

At least two envelopes at a Department of Defense mail processing center were suspected to contain the deadly toxin ricin, a Pentagon spokesperson said Tuesday.

Envelopes sent to the Pentagon may contain ricin, a letter sent to a Ted Cruz office contained white powder, and a suspicious letter was sent to the president.

A Pentagon spokesman says authorities found at least two packages suspected of containing ricin, a poison made from castor beans.

If the same white powder found in the most secure location on the planet had been ricin/anthrax would the investigation be concluded in one week without any suspects ?

I wonder how the @SecretService would’ve reacted to the white powder being Ricin?

Cocaine being found in the WH is a national security issue (sub in ricin for the cocaine). The fact that the Secret Service doesn’t think so, tells everyone that they know who it is. And, that person is being protected.

Yeah….Just a tourist, (terrorist) dropping off their cocaine (anthrax, sarin, ricin) in the White House….. Yeah…That’s what happened. Now we know why she’s a FORMER Secret Service Agent. (Stooge) https://t.co/MHEnn8M0Em

Shame how these agencies' operating budgets are in the billions and they are so inept that between them all, they "can't find" who placed a bag of cocaine in the White House. COULD HAVE BEEN RICIN!

The twist was in pretending I minimized the violence. I said there was some violence. Just like at the White House there was cocaine. It could have easily been ricin, they're pretending to give up because the culprit is likely highly inconvenient, SS down the corruption drain https://t.co/PxosRlQMiJ

People need to be fired over the incompetence. What if it had been ricin? Telling the truth would be a novelty. https://t.co/r6sawHlTit

If the cocaine had been ricin, do you think we'd know how it got into the White House?

I don’t remember another time where drugs were found at the White House & then to say that there is no way we will ever know who it was? Really? All ridiculous. No way a commoner walks into the White House with a bag of coke that could have been ricin and u can’t figure it out. https://t.co/gVJYEImOXe
