The double standard here is incredible. Harry Ried is doing two things democrats have been denouncing repeatedly, 1. Making accusations that are completely baseless for political gain, and 2. Saying an agency if the government is attempting to rig the election!
That's quite a stretch.
1) There's an actual probe by the FBI into Manafort's Russia ties. It involves another Trump campaign member too.
2) Reid mentioned that Comey bringing this letter out 11 days is a partisan move, since making information public violates DOJ guidelines. He did not say the election was rigged - there's a huge difference.
