From Heather Cox Richardson’s Letters from an American:
Intelligence officers from Special Counsel Robert Mueller to Russia expert Fiona Hill have warned us that Russia would disrupt this election, and we know they are already disrupting the Democratic presidential nomination process, trying to affect the way voters perceive the Democratic candidates.
This attack seems likely to go unchallenged by the administration. Trump has installed as our acting Director of National Intelligence the current Ambassador to Germany, Richard Grenell, who has made clear he does not believe Russia interfered in our 2016 election or that it is attacking us in 2020, either. Trump’s recent nomination of Representative John Ratcliffe (R-TX), one of the key defenders of the president during the impeachment hearings, seems designed to guarantee an end to any investigation of Russian attacks.
