In addition to interviewing Trump senior policy advisor Stephen Miller about the president's firing of FBI Director James Comey, Special Counsel Robert Mueller also may be looking into what Miller knew about George Papadopoulos' communications with Russian operatives during the campaign.
From Business Insider:
On April 26, Papadopoulos met with Joseph Mifsud — identified in the court filings as an "overseas professor" — for breakfast at a London hotel. There, Mifsud told Papadopoulos that he had learned from high-level Kremlin officials during his recent trip to Moscow that the Russians had "dirt" on Clinton in the form of "thousands of emails," the filings say.
Papadopoulos emailed Miller the next day.
"Have some interesting messages coming in from Moscow about a trip when the time is right," he wrote, the court filings say.
