“A letter addressed to the president containing a suspicious substance” was received Tuesday at “the remote White House mail screening facility,” the Secret Service confirmed Wednesday morning in an email to NPR’s Ari Shapiro.
We don’t have any more information at this time about what authorities think that substance might be. But this follows the news from Tuesday that an envelope sent to the office of Sen. Roger Wicker, R-Miss., tested positive for the poison ricin in initial tests.
There’s also a report this hour from ABC News’ Terry Moran that “@ABC has learned a SECOND letter sent to the US Senate has tested positive for the poison ricin.” It’s unclear whether ABC’s sources might be mixed up and that there’s only one new letter — to the president — or that there are now two additional letters.
We’ll watch for more and update.
