Trump chief of staff John Kelly was questioned by special counsel Robert Mueller's team: Report

President Donald Trump's chief of staff John Kelly has been questioned by special counsel Robert Mueller's team of investigators as part of a probe of possible obstruction of justice, a new report says. CNN reported that Kelly, who is reportedly on the verge of leaving the White House, answered a "narrow set of questions" from Mueller's investigators. That sitdown came after White House lawyers first objected to Kelly being interviewed.
