White House aides told to keep Russia-related materials

"The White House is simply taking proactive steps," an officials tells ABC News.

"The White House is simply taking proactive steps to push back against these false and politically motivated attacks," an administration official told ABC News Wednesday.

The directive follows a request last week by Senate Democrats to the White House and law enforcement agencies to keep all materials involving contact between Trump's administration, campaign and transition teams —- or anyone acting on their behalf —- and Russian government officials or their associates.

Similarly, the Senate intelligence committee, which is investigating Russia's role in the election, has also asked more than a dozen organizations, agencies and individuals to preserve relevant records, according to The Associated Press.
