Notice how Rudy G has gone quiet lately? I think after his incoherent meltdowns and nonsensic rants where he often implicated Trump in wrongdoings, he might have been advised that he was hindering rather than helping and maybe he should just STFU.
It’s not in his interest to be mouthing off and keeping it in the news cycle in the run up to the midterms. It’s pretty clear now that Mueller has entered a low key phase so it would be really daft of any of the GOP side to even mention the Russia investigation.
