It got almost no attention, but 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.”

So, it’s okay for Democratic senators to encourage Ukraine to investigate Trump, but it’s not okay for the president to allegedly encourage Ukraine to investigate Hunter Biden?

And then there is Joe Biden. In 2016, the then-vice president threatened to withhold $1 billion in U.S. loan guarantees to Ukraine if the government did not fire the country’s top prosecutor, Viktor Shokin. According to the New York Times, “Among those who had a stake in the outcome was Hunter Biden … who at the time was on the board of an energy company owned by a Ukrainian oligarch who had been in the sights of the fired prosecutor general.” The Post reports that it is “unclear how seriously Shokin — who was under fire by U.S. and European officials for not taking a more aggressive posture toward corruption overall — was scrutinizing Burisma when he was forced out.” But what is clear is that Biden bragged about getting him fired, declaring last year: “I looked at them and said, ‘I’m leaving in six hours. If the prosecutor is not fired, you’re not getting the money.’ Well, son of a b—-. He got fired.”
