Mueller's team added granularity to the topics it originally discussed with the defense team months ago, like the firing of FBI Director James Comey, according to one of the sources. But prosecutors including former Watergate prosecutor James Quarles III gave Trump's lawyers enough detail that the President's team wrote a memo with possible questions they expect to be asked of him. One source familiar with the matter said the President has vacillated on agreeing to an interview in recent months. Trump was interested in speaking with Mueller's team if the probe would end soon, as his lawyers had long promised, another source said. But once the President realized Mueller's work isn't nearing a conclusion, he's become more agitated and has lashed out on Twitter.
