As Mueller’s investigation into possible collusion between Trump associates and Russians winds down, an interview with the President remains an outstanding issue even as Trump’s attorney Rudy Giuliani said an interview would happen “over my dead body.” One source familiar with the matter summed it up by saying, “Mueller is not satisfied.”

People familiar with the talks describe the two sides as at loggerheads, with no meaningful discussion about the issue in about five weeks.

And the Trump team appears to have hardened its position. It’s told the Mueller team that prosecutors have no cause to seek follow-up questions in person after the President’s team submitted written responses to questions before Thanksgiving.
