I think that the House should begin its impeachment proceedings against Donald Trump or STFU about it and it should do so as quickly as possible. I do not know what another investigation would accomplish. I also think that impeaching a president with an approval rating over 30% would be political hara-kiri for the Democrats.
Keep in mind that “high crimes and misdemeanors” are whatever the House thinks they are.
That said and harkening back to things I’ve said previously I think that lots of politicians, mostly lawyers who should know better, are playing fast and loose with some serious accusations, e.g. “treason”. Whatever you think Trump did or did not do there is no case for treason.
However, in this post I want to ask a question about obstruction of justice. Is it possible for the President of the United States to obstruct justice solely by exercising his legal authority? It’s hard for me to believe it is.
