US President Barack Obama has ordered a report on cyber attacks and foreign intervention during the 2016 election.
The White House says the report will seek patterns of activity dating back as far as 2008.
"Unfortunately, this activity is not new to Moscow, we've seen them do this for years...try and meddle in elections and engage in similar activities in Europe and across Asia. So they unfortunately have a long record of this. But the president has made clear to President Putin that this is unacceptable," said a White House spokesperson Eric Shultz.
