Now let's look at Trump:
No 'grounds'. No Indictments of Trump. No trials against Trump. No testifying before grand jury. No charges brought against Trump. Articles of impeachment Introduced 07/12/2017 but the Muller investigation was not complete until March of 2019.
They moved to impeach over a year before the investigation was even finished. 100% unfounded accusation. Quite literally they want to impeach Trump over accusations so they can justify the impeachment by those accusations. They have brought no actual charges against Trump to impeach him over.
