(AP) Letters containing a suspicious white powder were delivered to The Washington Post, the Centers for Disease Control and Prevention in Atlanta and at least two other locations. All tested negative for anthrax or other pathogens, the FBI said Wednesday.
Debbie Weierman, spokeswoman for the FBI’s Washington field office, said all the letters appeared to be identical.
“The content of each letter is anti-American and pro-Muslim,” she said. “All initial field tests have turned out to be negative.”
Letters also were delivered to a Long Island, N.Y., cable TV station and a Denver location that Weierman said was believed to be a radio station. The Post and CDC letters arrived Wednesday, Weierman said. The Denver letter was delivered Nov. 4, FBI Special Agent Ann Atanasio said.
