Surely you've not forgotten 'Reset Button'?
If given a choice between NSA & FSB/KGB, I'll take neither, thank you. A 'Russia friendly administration' doesn't concern me any more than it did in 2009, and I seriously doubt Trump would have sold a quarter of our uranium production to Russia. Or given the green light and boatloads of cash to Iran.
I could care less about Trump's tax returns. Mine are (allegedly) private. So should his be. If the IRS is doing the job it's supposed to be doing, as opposed to political persecution campaigns, there's nothing illegal there. I've never been in favor of forcing politicians to make their tax returns public - sets a bad precedent and conditions people to believe we ought to have access to them if they interest us. No thanks, none of our business. If they choose to publish them that's fine & dandy but choosing not to publish them is not in any way disqualifying in my book.
