Republicans Name 8 Potential Impeachment Witnesses. Here They Are From the Daily Caller:  Here is the Republican list: Hunter Biden: The son of former Vice President Joe Biden, and a former board member for Burisma Holdings, a Ukrainian gas company that has been plagued for years by corruption concerns. President Donald Trump asked Ukraine’s president in a July 25 phone call to consider investigating whether Joe Biden pressured the Ukrainian government in 2016 to shut down an investigation of Burisma. Devon Archer: One of Hunter Biden’s business partners and a former Burisma board member. Alexandra Chalupa: A former DNC consultant who met with Ukrainian embassy officials during the 2016 presidential campaign. Chalupa, who is Ukrainian-American, dug up dirt on Trump campaign chairman Paul Manafort. David Hale: The undersecretary of state for political affairs. Hale testified in a closed-door deposition Wednesday. Tim Morrison: The former senior director for European and Eurasian affairs on the National Security Council. Morrison is one of only two individuals, including National Security Council’s Ukraine director, Lt. Col. Alexander Vindman, to have listened to the July 25 phone call between Trump and Zelensky. Morrison testified that he did not hear anything illegal on the call, while Zelensky, who will be called to testify by Democrats, said that he had serious concerns with what Trump said in the call. Nellie Ohr: The wife of Justice Department official Bruce Ohr, and a former contractor for Fusion GPS. Ohr told Congress in an Oct. 19, 2018, interview that Serhiy Leshchenko, a former Ukrainian lawmaker and investigative journalist, was a source of information for Fusion GPS, which peddled the infamous Steele dossier. Leshchenko, who has acknowledged having contact with Chalupa, helped publish information in August 2016 that led to Manafort’s firing as Trump campaign chairman.

He testified Oct. 3 that he did not witness a Trump quid pro quo to Ukraine. Republicans also want to hear from the whistleblower, as well as anyone the individual cited in the Aug. 12 complaint against Trump. House Democrats have backed off of their initial calls to have the whistleblower testify. They argue that the whistleblower is now irrelevant because other witnesses have corroborated the Aug. 12 complaint. https://dailycaller.com/2019/11/09/gop-impeachment-hunter-biden-nellie-ohr/
