Trump Will Be All Over This

The Obama administration received multiple warnings from national security officials between 2014 and 2016 that the Kremlin was ramping up its intelligence operations and building disinformation networks it could use to disrupt the U.S. political system, according to more than half a dozen current and former officials.

And that could simply be a brag.

As early as 2014, the administration received a report that quoted a well-connected Russian source as saying that the Kremlin was building a disinformation arm that could be used to interfere in Western democracies. The report, according to an official familiar with it, included a quote from the Russian source telling U.S. officials in Moscow, "You have no idea how extensive these networks are in Europe ... and in the U.S., Russia has penetrated media organizations, lobbying firms, political parties, governments and militaries in all of these places."

There was no explicit warning of a threat to U.S. elections, but the official said some diplomats and national security officials in Moscow felt the administration was too quick to dismiss the possibility that the Kremlin incursions could reach the United States.

...but hey, do what you want...you will anyway.
