The Post says yes, this is a big deal.

The emails between President Trump’s oldest son and an intermediary for the Russians provide the clearest indication to date that Trump campaign officials and family members were at least prepared to do business with a foreign adversary in the mutual goal of taking down Hillary Clinton.

No one should presume to draw definitive conclusions from the contents of the emails as to possible jeopardy for Donald Trump Jr., where the overall investigation that includes various threads is heading, or most specifically how it will end. That remains the purview of special counsel Robert Mueller and investigators for the House and Senate intelligence committees. But in terms of public disclosures, what came out Tuesday was as stunning as anything to date, described by people closely watching on the outside as both breathtaking and surreal.

One thing the news does, Dan Balz writes, is blow away Big Don’s claim last weekend

that “nobody really knows” whether the Russians meddled in the U.S. election and if they did whether they did so with the intent of helping him and hurting Clinton.

Funny, Little Don knew that was bullshit at the time, but did he alert anyone? He did not.

The emails read like something out of a cheap spy thriller or perhaps even as a falsified document designed to lure and entrap a willing but unsuspecting victim.

That’s what I said. I said it read like something a CIA agent might say to test someone.

They also happen to lay out information that is transparently damaging and that undermines those who have dismissed suggestions of possible collusion or cooperation between Trump associates and the Russians as fanciful or deliberately misleading.

But her emails!

Oh wait, that won’t work any more, will it.

The language in the messages to Donald Trump Jr. is conspiratorial and explicit. The president’s son was offered “official documents” that would “incriminate Hillary Clinton” and that would be “very useful to your father.” Trump’s son was also informed in the email that the information being offered was “part of Russia and its government’s support for Mr. Trump.”

That’s why I italicized it and then bolded it.

Trump’s son said Tuesday he was releasing the emails in the interest of transparency, but that decision came after the New York Times informed him that their reporters had the contents and were preparing to publish. Day by day, thanks to the Times’s reporting, Donald Trump Jr. has been dissembling about how and why a meeting with a Russian lawyer came about.

And after Don Senior has always been so nice to the Times, too.

When reporters from the Times first approached him about the meeting, he said it was primarily about adoption, then later conceded that he had been told the purpose was to present damaging information about Clinton. Now it turns out there was an explicit connection to the Russian government. His rapidly changing explanations left White House Chief of Staff Reince Priebus hung out to dry with his comment on Sunday that it was a meeting about adoption.

Well, lie down with Trumps, get up with syphilis and a 50 year prison sentence.
