Deputy Attorney General Rod Rosenstein told lawmakers on Wednesday that he has not identified any reason to fire Special Counsel Robert Mueller, despite growing calls from supporters of President Donald Trump to do so. Rosenstein added that if Trump ordered him to fire Mueller, who is leading the investigation into Russian meddling in the 2016 election, he would refuse to comply unless there was “good cause” to justify Mueller’s removal. “As I’ve explained previously, I would follow the regulation: If there was good cause, I would act,” Rosenstein told the House Judiciary Committee.
