The U.S. House House Judiciary Committee will look into a New York Times report that the FBI opened a counter-intelligence investigation into whether President Donald Trump has been working on behalf of Russia, the panel’s Democratic chairman said on Saturday. The Times reported that the probe began in the days after Trump fired James Comey as FBI director in May 2017, and said the agency’s counterintelligence investigators had to consider whether Trump’s actions constituted a possible threat to national security. Committee Chairman Jerrold Nadler, a democrat, said his panel “will take steps to better understand both the president’s actions and the FBI’s response to that behavior.” The White House on Friday called the report “absurd,” while on Saturday Trump aimed his criticism at Comey and the FBI in half a dozen tweets. “There is no reason to doubt the seriousness or professionalism of the FBI, as the president did in reaction to this story,” Nadler said in a statement.
