We've got a number of overlapping stories breaking out or in motion at the moment. There are two letters -- one to Sen. Wicker and another to President Obama
-- that are believed to have been contaminated with the poison ricin. In addition there are two 'suspicious package' situations currently in progress on Capitol Hill.
I would emphasize that neither of these letters got to within any physical proximity of their intended recipients. And there is still on-going testing to confirm definitively that it is in fact ricin.
With the suspicious package situations, remember quite often these suspicious package situations turn out to be false alarms. For the moment we're waiting to hear more.
We're publishing running updates on each of these stories here
Late Update 12:49 PM: CNN's Dana Bash is reporting that Capitol Police are now saying that the suspicious packages have been removed from the buildings and that the buildings are now open again for business
. The statement was less clear on whether there's been a determination about what the 'suspicious packages' were.
