He's trying to make it seem like a partisan exercise, with republicans being kept in the dark.

Everyone is ignoring that there are republicans already in the scif, already hearing all the testimony, already seeing all the evidence. They just have to be on the relevant committees, same as Democrats.

their anti-Democrat bias is in their DNA

All articles I've read state this including talking heads on both CNN and MSNBC. I was wondering why they keep calling it the Democratic Impeachment Inquiry. That can't be right. When I have time, I will research if they called it the Republican Impeachment Inquiry back during the bogus impeachment of BC.

...but last night before that happened I added this very important context (bolded) in place of vague implications of legitimate "investigations".

And it's still there! So, it should be difficult for right wingers to remove it. Please forgive the typos. I can't fix them now.

On October 3, 2019, it was revealed that Taylor had expressed, in text messages, concern that President Trump may have withheld aid to Ukraine unless they investigated two right-wing conspiracy theories. One, about alleged corruption in Ukraine involving former Vice President Joe Biden. The other, an attempt to deflect from the US intelligence communities' consensus determination that Russia hacked the DNC and interfered with the 2016 presidential election, by suggesting without evidence, that the DNC is hiding the hacked server in the Ukraine. The server conspiracy, is derived from, and in support of a third right-wing conspiracy theory. This one suggests that former DNC employee Seth Rich actually leaked the DNC emails and that Hillary Clinton had him murdered for it.

Implicit through Taylor's testimony is that Trump's goal in withholding the congressionally mandated military aid to Ukraine was to extort newly inaugurated president of Ukraine, Volodymyr Zelensky, into announcing an investigation into the theory related to Biden in a primetime American television interview. At the time, and through much of the proceeding nascent Democratic Party Presidential Primary Election season, Biden was the leading candidate, and seemed likely to be the Democratic Party challenger to Trump in the 2020 United States Presidential Election. Additional incentive was provided for Ukraine to do as Trump and Guliani suggested, by implying that Zelensky would get a state visit to the White House if he complied.
