Because Hillary lost, and the DNC was exposed.

The issue of Russia’s alleged interference in the 2016 U.S. presidential election has intensified an already deep and bitter partisan divide. Democrats and the broader progressive community argue that a hostile nation worked to defeat Hillary Clinton and install a president that Moscow could influence, perhaps even control. Those allegations have become increasingly shrill and over-the-top. In the process, they have chilled debate on U.S. policy toward Russia and created an atmosphere of intolerance and guilt-by-association disturbingly reminiscent of the McCarthy era in the 1950.
It is astonishing how outlandish some of the comments have become. A recent example was the speculation that MSNBC contributor John Heilemann engaged in when Devin Nunes, chairman of the House Intelligence Committee, sought to make public the memo that the committee majority approved about possible FBI abuses during its investigation of collusion between the Trump campaign and the Russian government. Heilemann asked Democrat Sen. Chris Murphy: “Is it possible that we actually have a Russian agent running the House Intel Committee on the Republican side?” It was the second time that Heilemann raised that absurd notion on air.
