House Intelligence chairman Devin Nunes has rebuffed calls to step aside the panel's Russia investigation, stating, "Why would I?"

Representative Devin Nunes was criticized by colleagues on Wednesday for calling a news conference to announce that the communications of members of the team that ran Trump's transition to the presidency were swept up in incidental surveillance targeting foreigners.

Donald Trump's personal communications were picked up by U.S. intelligence operations that were monitoring foreign espionage targets, a top Republican said Wednesday in a major twist in the real-life spy drama unfolding in Washington.
