Of course he won’t indict Trump. Instead, he’ll indict one of the kids and leave dark hints about Trump’s involvement.
The Mueller probe has always been about the 2018 elections - both to influence and to provide grist for the impeachment mill.
The plan was to conclude it in late summer to allow a crescendo to build by election day and to discourage cowardly Pubbies from supporting Trump.
Don't forget that Mueller is as dirty as the rest of them. He was appointed as Special Council to try and CYA for all of the 'deep staters'. Because if he fails, which he is failing, then all of the dirty, unlawful, unConstitutional deeds that the FBI, DOJ and others will be laid bare for all to see.
I think it was supposed to be for impeachment, just look at what people like Kerry and Soros have been telling people overseas.
