WASHINGTON, May 30 (UPI) — A letter addressed to President Obama that has been intercepted may contain the toxic substance ricin, the FBI said Thursday.
A FBI spokesman said the agency was investigating a “suspicious letter” found at a White House mail facility Thursday morning, The Washington Post reported.
The FBI spokesman said test results weren’t yet known.
A ricin-laced letter was mailed to New York Mayor Michael Bloomberg earlier this week. Earlier this year, several ricin-tainted letters were mailed to other Washington political figures, including Sen. Roger Wicker, R-Miss.
