December 6

That's when the:marhasag will hit the fan in the House Judiciary Committee.  Meanwhile, The Republican ranking member of that Committee sent a letter to the (Democratic) chairman on Saturday, requesting extra witnesses be added to the committee's first impeachment hearing, scheduled for Wednesday, December 4.  The ranking member, Doug Collins, also asked that Republicans have the opportunity to select some of those witnesses.

They might get "extra" testifiers, but I doubt they'll get the chance to decide who those folks should be.  To think otherwise would be to fall into a fox / hen-house type of reasoning.
