BLITZER: The following breaking news. Two pieces of mail sent to the Pentagon mail facility just tested positive for the poison ricin. The FBI is taking a closer look. Let's bring in our Pentagon Correspondent Barbara Starr. What can you tell us, Barbara, about these two letters?</s>BARBARA STARR, CNN PENTAGON CORRESPONDENT: Wolf, at this hour, the FBI is conducting a secondary round of testing, are trying to determine what they are dealing with. These two envelopes came in a postal service mail bag apparently yesterday. Initial testing and initial screening at the Pentagon mail screening facility indicated that they tested positive for ricin. What we want to say is this screening facility is outside the Pentagon and these two pieces of mail never entered the building. The 20,000 people that work at the Pentagon were never at any risk. One envelope was addressed to Defense Secretary James Mattis, who is traveling in Europe this week, and the othering to Admiral John Richardson, the head of the U.S. Navy. There's a good deal of concern about trying to determine what exactly has occurred here, and whether, in fact, the deadly agent ricin is fully confirmed to be in these two involves. The FBI now has the lead. They are trying to test them and figure out exactly what happened here -- Wolf?</s>BLITZER: Very disturbing, indeed. I'm glad they do the tests before the mail is delivered to the Pentagon. Barbara, thank you very much. Update our viewers when you get more information.</s>STARR: Absolutely.</s>BLITZER: Other breaking news we're following, President Trump speaking out on his Supreme Court nominee, saying it would be unacceptable if Brett Kavanaugh did lie under oath to Congress.
