Also, in impeachment news...

With the impeachment inquiry charging forward, President Donald Trump’s allies have defended his demand for political investigations from Ukraine by claiming that the government in Kyiv tried to sabotage his candidacy and boost Hillary Clinton in 2016.

[...]

But the Republican-controlled Senate Intelligence Committee thoroughly investigated that theory, according to people with direct knowledge of the inquiry, and found no evidence that Ukraine waged a top-down interference campaign akin to the Kremlin’s efforts to help Trump win in 2016.

[...]

The committee’s Republican chairman, Richard Burr of North Carolina, said in October 2017 that the panel would be examining “collusion by either campaign during the 2016 elections."

But an interview that fall with the Democratic consultant at the heart of the accusation that Kyiv meddled, Alexandra Chalupa, was fruitless, a committee source said, and Republicans didn’t follow up or request any more witnesses related to the issue.

[...]

In her Senate testimony, Chalupa denied serving as an intermediary between the Ukrainian embassy and the DNC and said she had been targeted by a Russian active measures campaign. Intelligence officials have since briefed senators on Russia’s attempts to pin blame for the 2016 interference on Kyiv as part of a disinformation operation.

[...]

Chalupa confirmed to POLITICO that she was questioned by the panel. A spokesperson for Burr declined to comment.

So, the Republicans have known Chalupa was not a DNC operative working with Ukraine since at least last fall, but that didn't stop Nunes, et al., from demanding Chalupa be called as a hearing witness over and over, in an attempt to make it appear to the public that she was.

Senate Intelligence Committee member Angus King of Maine, an independent who caucuses with the Democrats, declined to comment on what the committee has or hasn’t investigated.

But he said in an interview that he’s “probably been to between 20-30 briefings and hearings on this subject of election interference in 2016, and I have never heard one word about any culpability on the part of Ukraine.”

[...]

The Senate Intelligence Committee concluded in a bipartisan report—after conducting “interviews of key individuals who have provided additional insights into these incidents—that Russia hacked the DNC, and agreed with the intelligence community’s 2017 assessment that “Putin and the Russian Government aspired to help President-elect Trump's election chances when possible by discrediting Secretary Clinton.”

Two volumes of the committee’s final report, entitled “Russian Active Measures Campaigns and Interference in the 2016 U.S. Election,” have been released so far, and neither address the theory that Ukraine interfered in the 2016 election.

In Volume 2, however, which focuses on Russia’s use of social media to wage disinformation campaigns, the committee flagged another episode in which Russia sought to blame Ukraine for its own misconduct: specifically, the “menu of conspiracy theories and false narratives” Russia introduced in 2014 to account for the downing of Malaysian Airlines Flight 17.

Ressponses to the GOP claims of Ukrainian interference in the 2016 election are laid out in the article if you want to familiarize yourself with them all.
