Russian national security official says the U.S. sent Moscow 2 official requests for explanations about Russian meddling in U.S. elections.

The 1st one came a week before the presidential election, and the 2nd one came in early 2017. Russia says it responded "exhaustively."

Russia then asked the US to provide the IP addresses involved that were inside Russian....

US has provided those IP addresses and now silence from Moscow....

Information from US sources....Russia has sent nothing to the US requests..not even confirming the IP addresses were in fact Russian issued IP addresses...
