Republicans claim that this impeachment is a "witch hunt" and a waste of taxpayer money. I'd like to put up a comparison if I may:
Hillary Clinton Benghazi "Investigation"
Duration: 4 years
0 indictments
0 charges
0 convictions
Trump-Russia Investigation
Duration: 20 months
35 Indictments/Charges (Individuals) (thus far)
3 Indictments/Charges (Companies)
5 guilty pleas (thus far)
4 convictions (thus far)
Indicted: Paul Erickson, Roger Stone, Paul Manafort, Rick Gates, George Papadopoulos, Michael Flynn, Michael Cohen, Richard Pinedo, Alex van der Zwaan, Konstantin Kilimnik, 12 Russian GRU officers, Internet Research Agency, and Concord Management
Guilty Pleas: Michael Flynn, Michael Cohen, George Papadopolous, Richard Pinedo, Alex van der Zwaan, and Rick Gates
Over 202 Criminal Charges, including:
Conspiracy against the USA (2 counts)
Conspiracy to launder money (4 counts)
Bank fraud (17 counts)
Bank fraud conspiracy (10 counts)
Subscribing to false tax returns (10 counts)
Making false statements (6 counts)
In other words, the Benghazi investigation (which the GOP Congress supported to the end) took 4 years and accomplished nothing, while the current two-year investigation has resulted in, well, results.
