Russia Said to Be Leading Suspect in Breach of DNC Computers

Russia is a leading suspect in a hacking attack on the Democratic National Committee that resulted in the theft of e-mail and internal reports, according to a U.S. official with knowledge of the probe who asked to not be identified because the inquiry is continuing.

The Federal Bureau of Investigation is investigating the breach, which some U.S. lawmakers and cybersecurity specialists had already linked to Russia. The Russian government reiterated a previous statement denying involvement in the hack, spokesman Dmitry Peskov told reporters Monday. In a statement, the FBI made no mention of Russia and offered no details on where it was focusing its investigation.
