It will not go public. The whole goal of the thing is to keep the public's attention on "impeachment", so they will not pay attention to the numerous scandals ongoing which involve Biden and Democrats in general. Keep them focused and distracted on impeachment at all costs.
The Dems will keep this circus sideshow going for as long as they possibly can. Remember, the goal is not to impeach Trump. The goal is simply to harass and slander him as much as possible to keep him from doing real work. In their harebrained attempt to tarnish Trump right before an election, the Dems are making themselves look like fools.
These antics do appeal to a very small segment of seriously mentally challenged people. But most rational sensible people who understand the bigger picture, see the Democrats wasting time over nothing. The Dems are running out the clock until the next election. When their voters ask them what did they accomplish in their last term, the only answer Dems will have is, 'We harassed Trump as much as we could!' That is literally all they have to report. Other than screwing with Trump 24/7, the Democrats have accomplished nothing. Nothing at all. The Democrats have wasted, thrown away, the last three years chasing Trump around.
