Washington, May 30: A suspicious letter similar to the one sent to New York Mayor Michael Bloomberg has been intercepted at the White House mail room, a media report said Thursday.
Citing a report by CBS News, Xinhua said authorities intercepted the letter addressed to President Barack Obama that may have been contaminated with the deadly toxin ricin.
