How about these guys Tio Vinny, should we "impeach" them too...?
in May , CNN reported that Sens. Robert Menendez (D-N.J.), Richard J. Durbin (D-Ill.) and Patrick J. Leahy (D-Vt.) wrote a letter to Ukraine’s prosecutor general, Yuriy Lutsenko, expressing concern at the closing of four investigations they said were critical to the Mueller probe. In the letter, they implied that their support for U.S. assistance to Ukraine was at stake. Describing themselves as “strong advocates for a robust and close relationship with Ukraine,” the Democratic senators declared, “We have supported [the] capacity-building process and are disappointed that some in Kyiv appear to have cast aside these [democratic] principles to avoid the ire of President Trump,” before demanding Lutsenko “reverse course and halt any efforts to impede cooperation with this important investigation.”
And, when Hillary was the one colluding with Russians (uranium One, 145 million from Russians to the Clinton Foundation, her mgr and his brother (Podesta's) getting 35 million from Putin's bank, her paying 12 million for FALSE info on Trump, etc, Dems made Mueller and the media look at Trump only to find no evidence of collusion. Now Obama and Hillary asked Ukraine in 2016 to investigate Trump and Manafort. Joe Biden bragged about getting the Ukrainian prosecutor fired for investigating his son's company by threatening to withhold over 1 Billion in aide and again they point at Trump for making a call to look into this. And of course your left wing progressive media is a willing collaborator in these diversionary tactics.
