The Wall Street Journal reports that it "received more than a dozen envelopes containing an unknown white powder, and New York City police and hazardous materials crews are investigating the matter." Apparently one floor of the offices (located at the World Financial Center) was evacuated—the Daily Intel suggests it could be the one where Rupert Murdoch's office is located. Last fall, an envelope with a suspicious white powder was sent to the NY Times and another was sent to Reuters. Update: We're hearing there's now a "full hazmat response" at the WSJ offices and decontamination is being set up for people exposed on floors 9 through 11.
