As part of a tense day in Washington, the FBI reported Wednesday around midday that a second ricin-contaminated envelope sent to a mail processing facility in Washington, D.C. Its intended recipient appears to have been the president. At another point, two Senate office buildings were locked down, one due to a person who apparently was carrying suspicious envelopes. (Update: Capitol police say the letters found today weren't hazardous, but a man was still being questioned late Wednesday, according to the AP. Update No. 2: There's been an arrest made. More here.)
Fox News' Mike Levine reports on an FBI bulletin that identified the envelope intended to reach the president.
ABC News reports that the Secret Service has confirmed the discovery.

In a statement this afternoon, the FBI denied a link to Boston, which seems clear given the postmark date.

According to Fox News, the FBI released the contents of the letters.
The bulletin 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."
During his daily briefing, White House spokesman Jay Carney offered little new information, saying only that Obama had been briefed on the letters both last night and this morning.
