There are a few theories. One is that if you're about to get run over by a parade, you run to the front and pretend you are for it. Another is that there is no guarantee that this will pass the senate (though it seems like it will have broad bipartisan support). The final point is that Trump's department of justice will have a lot of control over what is released and what is redacted. Another possibility is that he really is innocent or there's simply no proof.
