You should be more careful of accusing people of falling for fake news when you are having such a hard time distinguishing fact from fiction.
"The inquiry reported that Trump withheld military aid[a] and an invitation to the White House to Ukrainian president Volodymyr Zelenskyy in order to influence Ukraine to announce an investigation into Trump's political opponent Joe Biden"

As far as the impeachment, if you don't see this as nakedly partisan, then I would advise you to try and expand the perspectives you look at current events from.
That the outcome of the Senate trial was partisan has more to do with party politics. Republican Senators weren't on the floor arguing that Trump did the right thing. They intentionally worked to minimize how much of the trial was able to reach the news cycle because they also knew what occurred was wrong. The whole thing was over in 4 days and it was run on a weekend to minimize exposure. You might recall the upset over how the Senate even voted to not call witnesses.
