Democrats do not want the public to know how they started the Russian collusion hoax or the Ukraine hoax

Byron York:

Why are House Democrats stonewalling questions about the identity of the Trump-Ukraine whistleblower?

Start by taking them at their word. Perhaps they really are concerned about the whistleblower's personal safety. They also know that, beyond a limited prohibition applying to the inspector general of the intelligence community, no law bars anyone, in politics, media, or anywhere else, from revealing the whistleblower's identity. So they worry.

But there is more to the story. Should the whistleblower have connections to prominent Democrats, exposure of his identity could be embarrassing to the party. And perhaps most of all, reading through the impeachment investigation depositions that have been released so far, it's clear that cutting off questions that could possibly relate to the whistleblower has also allowed Democrats to shut off any look at how the Trump-Ukraine investigation started. Who was involved? What actions did they take? Why did some government employees think President Trump's July 25 call to Ukrainian President Volodymyr Zelensky represented a lost opportunity, or poor judgment, while others thought it represented wrongdoing requiring congressional investigation?

Democrats do not want the public to know. And in that, their position is familiar to anyone who has watched Washington for the last two years: The Democrats' determination to cut off questions about the origins of the Trump-Ukraine investigation is strikingly similar to their determination to cut off questions about the origins of the Trump-Russia investigation. In both cases, they fought hard to keep secret the origins of investigations that have shaken the nation, deeply divided the electorate, and affected the future of the presidency.

From their point of view, it makes sense. Democrats were rattled by Republican efforts to uncover the origins of the Trump-Russia investigation. The Steele dossier, the use of spies and informants to target the Trump campaign, the Carter Page wiretap, the murky start to the Crossfire Hurricane investigation — Democrats resisted GOP attempts to reveal them all. But in 2017 and 2018, Republicans controlled the House. Then-Chairman Devin Nunes used the power of the House Intelligence Committee to unearth key parts of the story. Nunes' efforts eventually led to a Justice Department inspector general investigation whose results, expected in the coming weeks, could further damage the Democratic Trump-Russia storyline. And then there is the ongoing criminal investigation led by U.S. Attorney John Durham.

But Democrats now control the House. As they lead the Trump-Ukraine impeachment investigation, House Intelligence Committee Chairman Adam Schiff and other Democrats are applying the lesson learned from Trump-Russia: Do not allow inquiry into the or

This is part of the Democrat culture of corruption where they try to cover-up and suppress news of their coup attempt.  They are actively engaged in an obstruction of justice.
