Trump denounces reports of widening Russia probe

President Donald Trump is taking to Twitter denounce reports that the Russia investigation is widening to examine whether he tried to obstruct justice.

In a tweet early Thursday, Trump said: "They made up a phony collusion with the Russians story, found zero proof, so now they go for obstruction of justice on the phony story. Nice."

The Washington Post reported late Wednesday that special counsel Robert Mueller is seeking interviews with three Trump administration officials who weren't involved in Trump's campaign. Those officials are: Dan Coats, the director of national intelligence; Michael Rogers, the head of the National Security Agency; and Richard Ledgett, the former NSA deputy director.

Accusations of obstruction arose last month when Trump fired FBI Director James Comey. Comey told Congress last week that he believed he was fired "because of the Russia investigation."
