A letter addressed to President Trump has been labeled suspicious and is being tested for the deadly poison ricin, according to a Fox News report Tuesday evening.
The day prior, two letters addressed to James Mattis and Admiral John Richardson containing the same poison were discovered at the Pentagon.
The FBI confirmed earlier on Tuesday that they took possession of the envelopes that were sent to the Pentagon.
Additionally, two people were taken to the hospital Tuesday after a powdery substance was found in mail addressed to Sen. Ted Cruz’s Houston campaign office earlier in the day, as well. The substance, however, turned out to be harmless.
