....more getting up to speed:

July 20-22, 2009 Biden takes first visit to Ukraine early in Obama's presidency to tell Ukraine the new administration will be open to Ukraine and they have nothing to fear by the Obama administrations attempts to reset relations with Russia. President Yanukovych was already pro Russian and between the reset of relations under Obama and the Yanukovych pro Russian stance is probably what led to Russia taking Crimea.
Early in 2014 Britain demands and investigation into Burisma for money laundering and freezes the assets of Burisma's owner in Britain.
In Feb 2014 Ukraine protest topple presidency of Viktor Yanukovych, Biden goes there to deliver promises of economic, energy and governance assistance. In April 2014 Dennis Archer joined the board of Burisma followed shortly thereafter by Hunter Biden. As of 2/28/14 a firm owned by Archer and Hunter, Rosemont Seneca had an account balance of $4.00, over the course of 2014-15 that account grew to over 3 million dollars as seen in a court filing against Dennis Archer for money laundering scribd/document/404001731/Rosemont-Seneca-Partners-Court-File. To see the court filing put .com after scribd in the above address. (which is a current ongoing investigation) In June 2014 Joe Biden goes to Ukraine again with promises of 48 million is US aid at the new Presidents Poroshenko's inauguration. This is also the first suspected time that Joe Biden had the investigation requested by Britain against Burisma be shut down as the investigation gets shelved through 2014 through early 2015. Prosecutor Shokin was not the prosecutor during this time, he was the deputy prosecutor, he had no say in shutting down the investigation the first time. In Dec of 2014 Britain again demanded cooperation into their own investigation of money laundering by Burisma, in response the US sent letters asking Ukraine to cooperate yet nothing comes of it. In Jan 2015 a court orders Britain to unfreeze the assets of Burisma's owner as they can't prove the allegations they brought forth against the owner. The old prosecutor retired and Shokin became the chief prosecutor in Feb 2015.. When Britain when to the UN and fired off a fiery speech about the lack of cooperation in their investigation in Sept 2015 it was ordered that the investigation be re-opened, which Shokin did re-open the case, the same case he worked on under the former chief prosecutor who ordered it shut down. When rumors started to surface that Archer and Hunter would be questioned in the investigation Joe Biden showed up in Dec 2015 and ordered the prosecutor fired or he was going to withhold one billion dollars in loan guarantees. That was the second time Biden had the investigation shut down as the case was immediately transferred to the NABU, National Anti Corruption Bureau of Ukraine which was closely aligned to the US embassy in Kiev which ordered it shut down. It was one of three cases that were ordered shut down after the firing of Shokin, another case involved George Soros. Now forward to current times and the president of Ukraine Biden claims he spent more time talking to then his own first loses his re-election bid, that was April of this year. Four days after that election loss is when Biden decided to officially announce his bid to run for president after months of speculation. Coincidence? I think not. It is also the same month that the democrats changed the whistle blower law to include those who didn't have first hand knowledge. Coincidence again? I think not. I think you will find this is the third time Biden interfered to keep a lid on the investigations as they knew the old president was no longer there to protect them and that as soon as the new president came into office in July Trump would request they re-open the investigations, which is exactly what happened. The president who lost his re-election bid would have also had every reason in the world to help coordinate an election interference in the 2016 election as Ukraine was mad as hell that the president they ousted in the rebellion had just run off with billions of dollars that belonged to Ukraine...that president was helped getting elected by Manafort who worked for him as a political consultant, Manafort went to work for Trump so you can see why Ukraine had good reason why they wouldn't want to see Trump elected. So yeah there is a lot of questions of corruptions, one currently being dealt with in a court of law here in the US against Dennis Archer and Rosemont Seneca and there's only one person who always seems to be at the helm of hindering the investigations at it isn't Trump. You can't claim innocents or bogus conspiracies if nothing was ever allowed to be investigated. That's just plain common sense.
