Did the eldest son of Donald J. Trump just say something terribly incriminating?

Don Jr. has told the New York Times that he met with a Russian lawyer on the promise that the Russian had some dirt that the Trump campaign could use against Hillary Rodham Clinton.

Collusion anyone?

Isn’t that precisely what special counsel Robert Mueller is examining, whether the Trump presidential campaign worked hand in glove with Russian operatives seeking to damage Clinton’s presidential campaign?

The president denies any collusion. Indeed, there’s been no proof of any collusion. So far it’s all been speculation and allegation.

Now, though, Don Jr., has poured some fuel on the smoldering embers that keep producing all that smoke.

The Washington Post reported the Times story and took particular note of something that Trump the Younger said. According to the Post: “‘It became clear to me that this was the true agenda all along and that the claims of potentially helpful information were a pretext for the meeting,’ Mr. Trump said.

“Read that last part again: ‘the claims of potentially helpful information were a pretext for the meeting.’”

So, if the young man is telling the truth, he went into the meeting expecting to receive dirt on Clinton. Did he pass it on to Dad? Did Dad do anything with it?

This story is getting murkier by the hour.
