Something that possibly bodes ill for the good guys is that the Supreme Court has granted cert to decide the scope of the obstruction of an official proceeding statute. https://www.scotusblog.com/2023/12/court-to-weigh-in-on-scope-of-law-used-in-jan-6-prosecutions/
The issue concerns this language:
(c) Whoever corruptly—
(1) alters, destroys, mutilates, or conceals a record, document, or other object, or attempts to do so, with the intent to impair the object's integrity or availability for use in an official proceeding; or
(2) otherwise obstructs, influences, or impedes any official proceeding, or attempts to do so,
shall be fined under this title or imprisoned not more than 20 years, or both.
One judge in the 1/6 cases believed the statute was confined to records, documents, other objects and related physical items. The other judges and DC Circuit decided that "otherwise" meant any conceivable way, unrelated to physical objects.
The Supreme Court has a recent history of narrowly construing criminal statutes, which, broadly speaking, is for the good. Maybe not so much in this case.
If they do it here, it will knock out one charge against Trump and quite a few convictions of 1/6 defendants.
