Not just one source

Gee.   Why shouldn't Democrats be upset that, while Trump was able to make maximum political use of the FBI looking at what Clinton did with her email server, six government agencies were secretly investigating Trump's team getting money from Russia? The BBC alleges now (thanks fellas, but it's a bit late):

Last April, the CIA director was shown intelligence that worried him. It was - allegedly - a tape recording of a conversation about money from the Kremlin going into the US presidential campaign.

It was passed to the US by an intelligence agency of one of the Baltic States. The CIA cannot act domestically against American citizens so a joint counter-intelligence taskforce was created.

The taskforce included six agencies or departments of government. Dealing with the domestic, US, side of the inquiry, were the FBI, the Department of the Treasury, and the Department of Justice. For the foreign and intelligence aspects of the investigation, there were another three agencies: the CIA, the Office of the Director of National Intelligence and the National Security Agency, responsible for electronic spying.

As for the Russians having the dirt on Trump's bedroom antics, again the same reporter tells us that it's believed by many to be true:

And the former MI6 agent is not the only source for the claim about Russian kompromat on the president-elect. Back in August, a retired spy told me he had been informed of its existence by "the head of an East European intelligence agency".

Later, I used an intermediary to pass some questions to active duty CIA officers dealing with the case file - they would not speak to me directly. I got a message back that there was "more than one tape", "audio and video", on "more than one date", in "more than one place" - in the Ritz-Carlton in Moscow and also in St Petersburg - and that the material was "of a sexual nature".

Seems to me that things have gone awry somewhere when you had even the liberal media blowing up the significance of every damn internal Democrat email, and the widely misunderstood and exaggerated significance of how Hillary used her email server, and yet there was no proper reporting of actually explosive matters until now.
