I think the Republicans should save this Awwshit up and pile it on top of his immigration failure and expose his dealings with foreign governments and businesses via his son Bagman. Even the WaPo and NYT are admitting now that Joke knew about what his son was up to because of multiple meetings where he, his son, his business partners, and foreign business and government officials were all present at the same time.
That way, they hit him with multiple charges from mishandling classified documents, to refusing to enforce US immigration law, to corruption and money laundering. Maybe toss in failure to pay taxes.
Done correctly--something I won't be holding my breath for--the Republicans could probably get enough Democrats onboard to actually make it stick, but I doubt they will be able to carry it out.
