A few weeks ago.
Exactly, and that's probably why Nancy Pelosi decided to stay (at least) one step ahead and not wait for more evidence. Adam Shiff did well in making the case, thus forcing the Rebublicans to oppose (action --> reaction):

the period after the trial when the evidence is going to be presented to the American voters, and it's going to be made clear that the (Senate) Republicans were actively not trying to find the truth (thus violating their oath to protect the constitution).
Step 1 is to make sure that the people understand that the logical thing (from a truth-finding perspective) for the Senate to do, is to call more witnesses, which they won't because of the Republican majority.
A next step is disclosing the body of evidence that Lev Parnas has only started to reveal, as a personal insurance policy to avoid being 'eliminated':

One of the next things,
after the trial, may be an increasing pressure on revealing the role of Mike Pompeo, who has gotten 'surprisingly' little attention for his role in the scheme that he was fully aware of. Bolton was clever enough to distance himself from the 'drug deal'. Pompeo has larger ambitions, so he is forced to stay on board, until he bails to avoid being dragged under.
This also helps Pelosi to improve the odds of a Democrat winning the elections, despite the relatively 'weak' line-up of candidates ...
Brilliant, chapeau...
