No Loss If Entire Congress Wiped Out

Several members of the Congress received mail threatening a biological attack and containing a suspicious powder later found to be harmless as law enforcement officials warned that more letters could be on their way.

A number of media organizations and TV shows, including the New York Times and The Daily Show with Jon Stewart, received mail postmarked Oregon warning that letters had been sent to the Washington or local offices of all 100 U.S. senators and that 10 contained a deadly pathogen, a law enforcement source said.

House of Representatives Speaker John Boehner, the top Republican in Congress, received a letter containing a powdery substance at one of his offices in his home state of Ohio, a Republican aide said, adding that the powder was harmless.
