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?
