I would encourage you to read TPM’s editor Josh Marshall’s recent post "Trump & Putin. Yes, It's Really a Thing." Marshall closely and exhaustively fleshes out Trump’s reliance on the infusion of Russian money to keep his empire afloat after bankruptcy, a fact that the release of his income taxes might reveal.
“Trump's tax returns would likely clarify the depth of his connections to and dependence on Russian capital aligned with Putin. And in case you're keeping score at home: no, that's not reassuring.”
Marshall’s post is longish form, but dives deeply to draw a convincing picture of what may be driving Trump’s surprising fraternity with Putin. Has Russian money compensated for the fact that Trump can no longer do business with any American bank, but must rely solely on Germany’s Deutsche Bank? Is Russian capital driving Trump into Putin’s hand? A must read!
