Broad context, as in the scope of activity that Trump’s agents engaged in to extort a foreign government into investigating a political rival for his own personal gain. Trump ad nauseam refers to his “perfect phone call” as his sole part in the military aid for political dirt scheme, and implores everyone not to look more broadly at what was going on behind the scenes, which is exactly what all of the Senate Republicans, save that leftist Mitt Romney, chose to echo as well. And the criminal charges that could have been leveled against Trump in the impeachment articles were left out because they weren’t necessary for impeachment, but could still be brought to bear in the courts when his term is over.
So I guess in your bizaro world there was no reason to investigate the evidence of Russian election interference, and links between Trump campaign members and Russian operatives. Apparently the whole investigation was fueled by the imaginations of a bunch of leftists US justice officials who enjoy masquerading as Republicans. And that leftist in Republican drag Robert Mueller didn’t believe it was up to him to prosecute Trump’s potential criminal activity that was cited in his report, he thought that should be left up to congress through impeachment, or the criminal courts when he leaves office.
