"Special counsel Robert Mueller told President Trump's legal team that he could subpoena the president to appear before a grand jury if Trump refuses an interview with Mueller's team, Trump's former lead attorney told The Associated Press Tuesday night.The nature of the questions leaked this week, likely another leak from Mueller's office. This alone, repeated often from Mueller's office is but another example of prosecutorial misconduct, and in any other venue would be evidence enough of an out of control investigation. None of the leaked questions point to any specific misconduct, but look to be designed to trap Trump into lying under oath. More or less the "Have you stopped beating your wife, yes or no." Congressional investigations concluded showing absolutely no collusion took place, but Mueller apparently has gone past his mandate on that subject. I doubt that was the mandate at all at this point, this was simply an operation to get Trump at any cost.
John Dowd told the AP that Mueller raised the possibility of a subpoena during a meeting with Trump's legal team in March. According to accounts of the meeting first reported by The Washington Post and confirmed by Fox News, Dowd retorted: "This isn’t some game. You are screwing with the work of the president of the United States."
Dowd resigned as Trump's lead lawyer weeks later amid a dispute over how to answer Mueller's request for a presidential interview.
The meeting appears to have been the first time Mueller raised the possibility of compelling Trump to testify as part of his investigation into allegations of collusion between the Trump campaign and Russian officials ahead of the 2016 election."
