Is Mueller’s grand jury the first step to impeachment?

Also consider this: We are talking about the grand-jury stage, not a trial. Mueller would not have prove beyond a reasonable doubt the facts said to justify issuance of a grand-jury report. He’d just have to argue that there is enough suspicious conduct on the part of the president and his associates to warrant a report.

On the matter of Comey’s dismissal, for example, Mueller could contend that Trump himself told Russian diplomats that his purpose for removing Comey was to ease the pressure on him due to the Russia investigation — even though Trump had caused the public to be told that Comey was fired for mishandling the Hillary Clinton e-mails investigation. Mueller could add that, in the aftermath of Comey’s dismissal, it was discovered that (a) Trump’s oldest son had arranged a meeting with Putin-regime operatives in hopes of obtaining information damaging to Hillary Clinton; and (b) when the New York Times learned about the incident, President Trump intervened by directing his son not to disclose that the reason for the meeting was to get dirt on Clinton (i.e., the president had his son deceptively represent that the meeting concerned American adoptions of Russian children).
