A letter addressed to President Barack Obama that contained a âsuspicious substanceâ has been intercepted at the White Houseâs off-site mail facility, a Secret Service spokesman said.
The Secret Service said it was not immediately clear what the substance is. It is also not known whether there is a connection with the letter sent to Sen. Roger Wicker (R-Miss.) containing the toxic poison ricin that was detected Tuesday.
Spokesman Edwin Donovan said the letter was received at the Secret Serviceâs White House mail screening facility, which examines all mail for the complex and is not located nearby. The facility, he said, âfacility routinely identifies letters or parcels that require secondary screening or scientific testing before delivery.â
