It should also be noted that when Mike Pompeo was heading up one of the Benghazi Inquiries, he demanded tens of thousands of documents from the State Department, and then castigated Hillary Clinton's State Department for not producing the documents fast enough, and threatened to charge the Obama Administration with Obstruction of Congress, because they took too long.
Pompeo's State Department has refused to turn over a single document and has tried to block staff from testifying.
No doubt the hypocrisy of Repubs is just stunning. There are no shortage of examples from Pompeo, Graham, Gowdy, Jordan, etc.
There's going to be a ruling on the McGahn case on Monday. I don't see how the court can rule he will not be compelled to testify unless the decision is left to Trump appointees. Once the ruling is made it gives the obstruction charge even more substantive legal backing. It is not disputable that Trump has obstructed a fully authorized impeachment inquiry...........just as Nixon did. It only takes one count of the articles of impeachment to pass to remove the prez. I don't see how the Repubs can vote against the charge of obstruction without twisting themselves in knots.
