U.S. Vice President Joe Biden told NBC, Censor.NET reports.
"We're sending a message [to Putin - ed.] and it will be at the time of our choosing, and under the circumstances that will have the greatest impact," Biden said.
When asked if the American public will know a message was sent, the vice president replied, "Hope not."
the U.S. government formally accused Russia for the first time of cyber attacks campaign against Democratic Party organizations ahead of the Nov. 8 presidential election.
U.S. intelligence officials concluded weeks ago that the Russian government was conducting or orchestrating cyber attacks against the Democratic National Committee and the Democratic Congressional Campaign Committee, possibly to disrupt or discredit the election, in which Democrat Hillary Clinton faces Republican Donald Trump.
Kremlin as usual refuses to admit its involvement into the attacks. Moreover, a Kremlin spokesman called the U.S. allegations "nonsense".
