Federal officials responded to a bomb threat at NPR in Washington, D.C., on Monday, nearly a week after the controversial firing of Juan Williams, the FBI tells Fox News.
Federal agents with the Joint Terrorism Task Force collected a letter that was received in the mail, the FBI said Tuesday. It is now in the bureau's custody. There is no word on what was said in the letter.
The Washington Post reports that NPR warned its employees about a general "security threat" in a staff memo Monday.
"We're taking extra precautions today," NPR spokeswoman Anna Christopher told the Post on Tuesday. "We're being more aware of who's entering the building."
The station has received thousands of e-mails and phone calls since the dismissal of Williams last Wednesday.
NPR fired Williams for comments he made on Fox News' "The O'Reilly Factor" in which he said he gets worried over flying on planes with people wearing "Muslim garb." He said later in the same interview that it's wrong to racially or religiously profile people.
