The So-called 'Impeachment Inquiry' is nothing but a Dog & Pony Show until it's Voted on,
And no-more on the level than Nosy Cops knocking on somebody's door to investigate a nasty rumor started by Gossiping Hags & circulated by mean middle-school girls because they hate their odd looking neighbor's patriotic Porch-Flag , Pink Flamingos & Garden Gnomes.
And that's NOTHING that anybody in the White House is obligated to cooperate with including even the President.
The 5th Amendment & the Right to remain silent and even say NO to bogus "Inquiries" is NOT 'Obstruction of Justice",, it IS justice!
So Democrats need to put their money where their Mouth is & VOTE on impeachment or just STFU,,,
And in the meantime, if the Dems want Trump out of the White House they're gonna have to do it the old fashioned way & either Win an election or just get the Deep-State to work blowing the dust off of the old "Dallas '63" playbook ,,,
