Maybe he doesn't want them withheld and, knowing that all previous presidents kept the documents of presidents before them classified, he asked Joetato to withhold his knowing that Corn Pop would do what he thinks will hurt Trump.
Too big of a stretch?
I think this is likely. If they release it, then there won’t be anything there for them to go after (unless, of course, evidence has been planted and the report changed).
If the White House withholds the report, then it looks like Biden is hiding something.
Either way, this is a win for a Trump.
