What prevents Robert Mueller from simply saying:
"We couldn't fully prove Trump's campaign conspired with the Russians during the election, but we came very close. What we did prove, multiple times, was that Trump and others close to him did obstruct justice by, among other things, lying to investigators and shutting down investigations.
"Since the Justice Department won't allow us to indict a sitting president, we recommend, strongly, that Congress initiate impeachment immediately.
"Furthermore, we recommend that the US take immediate concrete steps to ensure that no foreign power can do what Russia did in 2016 or worse."
