A senior White House official is reportedly being identified as a "significant person of interest" in the Russia investigation.  The Washington Post says the man or woman is someone close to President Trump. 

The investigation of Russian meddling in the presidential election includes allegations of collusion between Moscow and the Trump campaign.  The White House has consistently rejected any claims of collusion. 

Former FBI Director Robert Muller  has been named as a special counsel in the growing Russia probe.  In a news conference this week, Trump called the investigation a "witch hunt."
