According to John Solomon’s article entitled Senior Ukrainian official says he’s opened probe into US election interference
posted March 20, 2019, at 10:33 AM EDT, online at The Hill, “Ukrainian Prosecutor General Yuriy Lutsenko … is probing a claim from a member of the Ukrainian parliament that the director of the National Anti-Corruption Bureau of Ukraine (NABU), Artem Sytnyk, attempted to the benefit of the 2016 U.S. presidential election on behalf of Hillary Clinton.”

Solomon’s article suggests that NABU’s Sytnyk provided the allegedly damaging financial information about Paul Manafort’s business dealings in Ukraine specifically to undermine the Trump campaign and to provide support for the Clinton campaign.

Sounds like meddling by a high-level Ukraine official (Sytnyk) in the US presidential election.

Someone might wonder what benefit Sytnyk received in advance or was promised after Clinton became President.   And who provided that benefit?
